Re: Problem sometimes Freebsd crash

You can edit kernel parameters in /etc/sysctl.conf and in
/boot/loader.conf. You typically enter setting changes in /boot/loader.conf
when the values can only be set at boot time or as the kernel is being
loaded. Things like setting shared memory sizes, nmbclusters, etc. are best
put in /boot/loader.conf and typically you'll receive a warning in
/var/log/messages if you place a setting change in /etc/sysctl.conf that
really belongs in /boot/loader.conf.
However, what I was wondering is if you used the kernel that comes with
bwmgr - the kernel that Emerging Technologies provides or if you kept the
GENERIC kernel that comes with the typical FreeBSD installation. It might
be best to use ET's kernel as it probably was compiled with the appropriate
mbuf settings and nmbclusters, etc.
One last consideration - if you adjust the size of nmbclusters in your
/boot/loader.conf file, sometimes you need to increase the size of some
other settings. What settings have you set in /etc/sysctl.conf and/or
/boot/loader.conf ?

I have to solve this problem. Perhaps, I do not sure, but I believe
that I would edit kernel parameters in /etc/sysctl.conf
I have seen tunning with postgresql and freebsd, mysql and freebsd, I
have found examples about it.
Are there links about it? What are parameters corrects for edit memory
in sysctl.conf?

You may need to talk directly to Emerging Technologies - especially if
you're using their licensed version of the software and not the demo.
They'll probably be a lot better at helping you troubleshoot this

help you out, reply with some additional information about your systemlike
the hardware specs and your custom kernel config, if you built one.
Good Luck,

Hi friends,
My name is Jorge, i am from Peru, excuse me for my english, I have a
server with FreeBSD 4.11-RELEASE #2 and Bandwitdh Manager (bwmgrd),
but I have many problems with it, I have rise up mbuf clusters in my
server to 16384 (It I have made in the file /boot/loader.conf), before
It was configured to 12000. Now I do not have logs about

However, sometimes my server still hang, crash. I have to reboot the
server for that I work again. If I have enough memory, why bwmgrd no
use it, I do not why it said 59 requests for memory denied
There are some logs
#netstat -m

This is report of my server memory
