I've now got a bit more informatio= n=20 but still no solution. I am looking for a way to debug this anyway I can. We got a freebsd 6.2 (FreeBSD =A06.2-RELEASE FreeBSD 6.2-RELEASE #0) machin= e=20 running if_bridge as a intercept proxy. We have added the following kernel options: options=A0DDB options=A0KDB options=A0BREAK_TO_DEBUGGER options=A0INVARIANTS options=A0INVARIANTS_SUPPORT options=A0WITNESS options=A0DEBUG_VFS_LOCKS options=A0DEBUG_MEMGUARD We were getting an LOR but fixed it but removing "kern.polling.enable"=20 in /etc/sysctl.conf As of right now the machine goes into dead lock within a few hours (only wh= en=20 on the network). I get no WITNESS errors (LORs), or kernel dumps, or=20 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 =2D--DMESG output---- Copyright (c) 1992-2007 The FreeBSD Project.
