Re: How to diagnose crashes?
Chris, The 5.3 have this problem. I think it has something to do with ACPI. Either go back to the 5.2 or pick the latest. You say the system reboots itself from time to time. Is it a panic you see before the reboot? There must be an option to turn on somewhere asking them to write to disk the contents of the physical memory. You can, then, run gdb on the dumped core. I think I have seen someone do that on NetBSD.

In my case, the reboots seem to be related to the kernel TCP/IP stack. The box reboots under network load way too often. I don't suspect any other hard problem with it. It handle kernel builds and makeworlds w/o incident. MemTest86 did not find any problems with the memory. I have seen some other posts on this list about this issue. The posters thought it was a problem with SMP kernels. I compiled a uniproc kernel and just had another spontaneous reboot last night! After looking for .core, you may want to capture /dev/console messages to a log file. I am assuming since the box is colo'd, you don't have console access. You may still miss some output though.
