>Description:
machine have 2 bce interfaces both on board.
one is used as WAN other as LAN (IP 10.20.40.1)
i use ipfw with pipes and queues.
it worked fine under FreeBSD 7.3
With new FreeBSD i'm getting problem like 10.20.40.1 not responding LOCALLY.
i can ping it from any computer at local network, but when i log in into server
and do
ping 10.20.40.1
i'm getting no buffer space available.
ifconfig bce1 down;sleep 1;ifconfig bce1 up
"fixes" the problem until next some hours, sometimes few days but never more.
ipfw and network configuration was not changed even a bit after moving from 7.3
i use FreeBSD 8 on other machines but not with bce interfaces with similar
style ipfw configuration, without any problems.
I'm not sure it is ipfw related, as i can't stop ipfw for test (it's production
machine). i just added workaround now to reset bce1 every 10 minutes.
>How-To-Repeat:
use bce interfaces with FreeBSD 8 and ipfw.
I am not 100% sure if it's related to bce1 but i have such problem only on THAT
server which was running fine with FreeBSD 7
(but slower, ahci driver from 8.* is really worth of update)
>Fix:
no idea what it is. adapter is actually working, it's some kind of routing/ipfw
problem.
please reply to e-mail if you need detailed configuration.
