Ynt: Re: 6.1 STABLE Strangely Hangs when VLAN enabled.

Hi,

Freebsd 61 hangs 4-5 times per day,

i didnt test via single vlan.
i have no crash dump, even makeoptions=-g configured.
kernel doesnt panic, system only hangs :(

I tried both Hyperthreading enabled/disabled.
I tried both SMP Kernel / Non-SMP Kernel.
The answer is same.

This server's job is mainly a DMZ Firewall.

Jobs:
- apache2.0 for web management
- ng_nat (nat for each vlan, 9 ng_nat configured)
- two natd daemon for port forwarding and static nat
- dhcpd
- only ipfw
- vlan logic interfaces used for ipfw rules
- ipfw tables used
- mpd for incoming vpn connections
- bge0 is connected to LAN (VLAN is on this interface)
- bge1 is connected to ATM Router directly
- em0 is connected to DMZ Switch
- em1 is disconnected

Thanks for your interests
Best Regards,

Rmkml <rmkml@xxxxxxx> :

Hi ozkan,
how many times per day freebsd61 hang ?
if you only 1 vlan, do you have hang ? (two ?, three ?...)
do you have crash dump ?
you have one physical processor, but do you have hypertreading enabled ?
what jobs srv have ? (vlan ok, ipfw ?, ipfilter ?, pf ?, smtp ?, ....)
possible check with top/netstat if you memory fill ?
do you use ipfw/ipf/pf with vlan logic interface ?
do you use two bge interface or only one ?
same question for two em interface ?
Best Regards
Rmkml

Subject: 6.1 STABLE Strangely Hangs when VLAN enabled.

Hi,

I have a HP DL380-G4 server.
Single Xeon 3.0Ghz cpu, two onboard bge NICs and one dual em NIC.

I am using vlan interfaces on bge0 (there is 9 vlan interface on bge0). But
systems hangs at a random time without any logs/errors and even panic message!
Before system hangs everything works normally. (OS: 6.1 STABLE-200609)
After this problem I tried 6.1 STABLE-200607. Same result!

After removing vlan support from kernel, everything became normal.

I installed same system to another pc (P4-1.4Ghz NICs: rl).
When VLAN enabled, system hangs at a random time again.
I got crazy.

What the problem can be? How can i debug the problem?


Used These Options on That Kernel:

options IPFIREWALL
options IPFIREWALL_VERBOSE
options IPFIREWALL_VERBOSE_LIMIT=100000
options IPFIREWALL_DEFAULT_TO_ACCEPT
options IPDIVERT
options DUMMYNET
options IPSTEALTH
options TCP_DROP_SYNFIN
options NETGRAPH
options LIBALIAS
options NETGRAPH_NAT
options NETGRAPH_IPFW
options NETGRAPH_SOCKET
options NETGRAPH_IFACE
options NETGRAPH_PPP
options NETGRAPH_BPF
options NETGRAPH_VJC
options GEOM_BDE
device vlan

Have an idea?

Thanks by now.
