I ran into a similar problem with the BSD allocator running under heavy
load that didn't happen under any Solaris or Linux system I used. I
finally fixed it by using Doug Lea's malloc just for this one application:
http://shell.siscom.net/~vogelke/Software/Languages/C/Libraries/malloc/
This was under FreeBSD 6.*, but it might provide another data point if you
want to give it a try.

I'm not sure how similar the two problems are. I quite frankly know
_very_ little of what the original problem was, other than "I am
encountering issues where values just seem to arbitrarily change".
Memory exhaustion is a potential problem with almost any sort of
allocator that fragments memory in any way, but random corruption of
user data is probably a different issue :/
If you have some sort of description of the workload that triggered the
memory exhaustion with jemalloc (the current malloc implementation in
FreeBSD), it's probably a good idea to talk to Jason Evans about it (his
email is "jasone" at FreeBSD.org). He may be able to help you tune
malloc or even make changes to the system version of malloc that make it
less vulnerable to this sort of problem.

Hi, list!
I have a private home network, on an ADSL2+ connection to the
internet. The home network is behind NAT, all automatically set up
by the router/dhcp server/wlan access point/adsl modem that I got
from my ISP. It's a Thomson SpeedTouch 585 router.
Now, on this network, most of the computers get their IP by means of
DHCP. Except our home audio server, which have a hard coded ip
address in rc.conf, set to something within the range of the dhcp
server (10.0.0.2-10.0.0.253). The server seems to pick this up, and
don't give that address away to someone else.
I've tried using other addresses outside this range, like 10.0.1.1,
but that doesn't work. All network access is lost when I do that.
Now, on my local network I'd like to put a diskless machine. As I
understand it, my DHCP server needs to tell the client about the
"filename" and a "next-server" to use. I don't think I can setup the
Thomson router to do this. All the instruction I can find online
advises me to install a DHCP server on the same machine that serves
the pxe boot image. But if I do that, I'll get two DHCP servers on
my local network. Is that ok? Will there be a race condition, when a
client asks for an IP address?

You may also want to ensure that the router will never allocate your
static IP address to someone else.
Look at the DHCP router settings either for DHCP scope (set it to
narrower values, and use a static IP outside the range) or for something
like exceptions / exclusion where you can mark a specific IP that DHCP
will never assign.
I've tried using other addresses outside this range, like 10.0.1.1,
but that doesn't work. All network access is lost when I do that.
10.0.1.1 is a different network (I assume your netmask is
255.255.255.0, but check your router or your clients)

You will have to shutdown the router's DHCP. Probably disable it
permanently and assign this function to a machine.
The DHCP of the router also sends you the following information (besides
IP address):
- DNS Server(s): Either the ones used by your ISP (consult its website)
or its own address (i.e. 10.0.0.1). Most routers send their own address
as a DNS server and perform the resolution by sending your request to
ISP servers.
- Gateway address: This is always the router's local IP address (i.e.
10.0.0.1)
If you setup your own DHCP server, make sure it is set to send this info
as well. (These are commonly known as DHCP options)

Yes, there is a problem. See my posting here:
http://lists.freebsd.org/pipermail/freebsd-questions/2008-June/177553.html
Unfortunatelly, I have not got an answer, but it is obvious packages
using this new symbol must fail:
http://lists.freebsd.org/pipermail/cvs-src/2008-May/091586.html
The question is, if other package may fail as well.
I have had one more error that went away after recompiling a STABLE package:
http://lists.freebsd.org/pipermail/freebsd-gnome/2008-July/020520.html
I do not know if this is related, though.
If you find out more, please, let me know.

Just to add to that suggestion, if you have a separate DHCP server,
make sure your router works as a DHCP client for the internal network
as well. You should be able to do that by telnetting into the
management port. You may use a serial cable as well.
This is required in order to get the NAT working properly.
Thanks

Yeah, but even though the router has customizable values for this

What are you trying to set it at? I would just lower the 253 value, so I
could use the upper end for my static addresses. If you try to set it to
a subnet outside it's own address, it will definitely not accept it.
I would also try a factory reset or firmware upgrade of the router. I
have been using a Speedtouch 500 series for years, and never had any
problems with settings not getting registered. AFAIR the 585 has one of
the new web interfaces and it is kind of confusing. I found the 500
easier to use.

You're right! But how do I make the entire 10/24 adress space

Well problem is, a netmask of 255.255.255.0 means only the last octet
can be used for hosts. Your DHCP server is already assigning addresses
from this space.

Yes. As long as the clients have a valid DNS to ask, and a valid gateway

think about it, you are already doing this on the system with the static
configuration.
Is there a way to debug the DHCP response from the current router

sv.
Not sure about this, sorry. However, don't expect much more than
IP/Netmask, DNS Server, Gateway from a simple router. These should not
be difficult to configure in isc-dhcp3 (net/isc-dhcp3-server).
Have a look at this article:
http://www.howtoforge.com/dhcp_server_linux_debian_sarge
It is linux oriented, but very easy to adjust for FreeBSD.
You will also need to add:
option domain-name-servers 10.0.0.1;
to set the DNS server address to your clients.

Well, I changed it to 255.255.254.0 (0xfffffe00) but kept the dhcp
range as it was.

Yes. As long as the clients have a valid DNS to ask, and a valid gateway

think about it, you are already doing this on the system with the static

Ok, I will look into this.
Also, looking through the telnet interface options (which are far
more than the web interface gives), I see that I can add "dhch
server option templates", "dhcp server option instances" and that I
can assign such an instance to the "dhcp server pool options".
This uses a different config scheme than the isc dhcp server config
files, though. And it seems I need to create a template before I can
create an instance. The template takes a name and an option id as
paramters. The instance, then takes a name, a template, and a value
as mandatory paramters. Also enterprice number, suboption number,
and more.
How does the "filename", "next-server", etc map to option ids? Are
these isomorphic, or do I get this completely wrong?
Does this make any sense to you, or anyone else here? Should I try
to make the router DHCP server serve the right options, or would you
go the isc dhcp route?
Thank you very much for your help so far!

keep the default dhcp address space as 10.0.0.2-10.0.0.253. Now I
seem to be able to use 10.0.1.1/24 for my own private use.
(I don't think I really know what I'm doing here, but it works!)
Well, a netmask of 255.255.254.0 should give you 10.0.0.1 to 10.0.1.254
host addresses.
10.0.1.1 is within range, it should work.
Well problem is, a netmask of 255.255.255.0 means only the last octet
can be used for hosts. Your DHCP server is already assigning addresses
from this space.
Well, I changed it to 255.255.254.0 (0xfffffe00) but kept the dhcp
range as it was.
The DHCP range you are assigning is a subset of what you allowed with
the netmask, thus it is valid.
So as long as I make my own DHCP server act the same way as theYes. As long as the clients have a valid DNS to ask, and a valid gateway
router one, I should be fine? NAT and all will work?
to send their packets, everything will work properly. If you come to
think about it, you are already doing this on the system with the static
configuration.
Ok, I will look into this.
Also, looking through the telnet interface options (which are far
more than the web interface gives), I see that I can add "dhch
server option templates", "dhcp server option instances" and that I
can assign such an instance to the "dhcp server pool options".
Ah, yes completely forgot the speedtouch has a telnet interface as well.
I messed with it a few times myself, mostly for fun ;)
This uses a different config scheme than the isc dhcp server config
files, though. And it seems I need to create a template before I can
create an instance. The template takes a name and an option id as
paramters. The instance, then takes a name, a template, and a value
as mandatory paramters. Also enterprice number, suboption number,
and more.
How does the "filename", "next-server", etc map to option ids? Are
these isomorphic, or do I get this completely wrong?
Does this make any sense to you, or anyone else here? Should I try
to make the router DHCP server serve the right options, or would you
go the isc dhcp route?
Thank you very much for your help so far!
sv.
I have only done PXE with Windows servers, and it has been quite some
time - cannot remember the details.
I certainly would not advise you to use the router for this - even if it
is possible it has several drawbacks.
- You will, sooner or later, change the router and your new one may not
have the capability
- You will spend a probably unreasonable amount of time trying to make
it work - and it may not even succeed
- Learning how to perform this on FreeBSD will help you apply it in many
other situations.
I would definitely go the isc-dhcp route.

I have a problem with a box I upgraded from FreeBSD 6.2 To FreeBSD7
It seems the following is happening when I try use portupgrade -a or even
building ports.
ALL transfers that are FTP fail.
Now to make this simple, I have following environmental variables set..
http_proxy=http://192.168.12.4:3128/
ftp_proxy=http://192.168.12.1:3128/
FTP_PASSIVE_MODE=YES
And here is the strange thing..
Fetch fails, but if I use wget there is no problem.
The firewall does allow ftp to go directly aswell, so I have also tried
leaving out any and all proxy settings, this fails aswell. (Except for wget
once again)
And here is the crux.
I have 5 mahcines on SAME network that has no issues like this, so this
makes me think fetch is broke somehow.
How can I force FreeBSD to use wget instead of fetch to bypass this?
Ive tried setting env FETCH_CMD=wget but that results in wget failing with
msg:
Try `wget --help' for more options.
=> Attempting to fetch from http://mirror.sg.depaul.edu/pub/security/nmap/.
wget: invalid option --
Usage: wget [OPTION]... [URL]...
Thankx ahead!

You might want to add `DISABLE_SIZE=YES' to your /etc/make.conf, as the
fetch's -S option confuses wget. FWIW I use that in connection with
`FETCH_CMD=wget -c --passive-ftp' in make.conf and it has been working for a
long time for me.
