Good Day,
I've brought up this issue in the past. I've now got a bit more information
but still no solution. I am looking for a way to debug this anyway I can.
We got a freebsd 6.2 (FreeBSD 6.2-RELEASE FreeBSD 6.2-RELEASE #0) machine
running if_bridge as a intercept proxy.
We have added the following kernel options:
options DDB
options KDB
options BREAK_TO_DEBUGGER
options INVARIANTS
options INVARIANTS_SUPPORT
options WITNESS
options DEBUG_VFS_LOCKS
options DEBUG_MEMGUARD
We were getting an LOR but fixed it but removing "kern.polling.enable"
in /etc/sysctl.conf
As of right now the machine goes into dead lock within a few hours (only when
on the network). I get no WITNESS errors (LORs), or kernel dumps, or
anything in the logs that look like an error or out of the ordinary.
Is there anything else I could try? or am I looking at a hardware failure?
see demsg below.
Roger
