Originally I thought it was exim, or possibly bind, or bad hardware (mb, cpu or memory)... I've swapped out the motherboard & CPU's & memory from an old server that was running 4.11 ROCK SOLID for years... At first I thought the problem was solved, but now it's popping up again... The 2nd CPU gets 'shut down', or kernel panics, esentially taking the system offline. If I install a single CPU (non-smp) kernel, then the system works fine... (I did this on the old motherboard before I swapped it out, and it worked fine too).. So I'm wondering if there is an SMP bug or problem I'm running into. I'm running 6.1-STABLE-200608, an ISO image I downloaded from the archives when I built the box (NOT 6.1-RELEASE). I'm runining an Intel Serverworks motherboard with 2 1.4 GHz PIII's... The problem only seems to show up under high load. I'm wondering what I should do here... I'm concerned about doing a binary upgrade to 6.2 won't fix the problem, and I've tried using freebsd-update, but it complains about the version not being compatible. If I do a binary upgrade from CD, will it also update the kernel sources so I can build a new one? Will it complain about it not being compatible? Is there a way to 'force' the ID of the system to be 6.1-RELEASE so that freebsd-update will work? Will doing the 6.1-6.2 binary upgrade as posted by Colin also update the kernel sources? Would my best option really be to start over with a fresh install rather than upgrade? (this would be painful) I'm going to try to test out 6.2 on the old MB/CPU combo to see if I can re-create it under 6.2 as well before I do anything. As well as try doing an upgrade on the bench from CD from 6.1-STABLE-200608 to 6.2-RELEASE... Since this is a production server (and for months it was burned in with no apparent issues) I only have 1 shot at this to do it right. Any help/recomendation would be appreciated.
