I'm probably going to complete screw this up:
Last night one of our test machines wedged while under a rather
moderate load. We were able to recover the oops from the serial
console (screen is your buddy):
At the time of the crash the machine was running Mysql 3.23.43 with
a rather large dataset--probably filling the available memory space.
The machine has been run hard for a couple days (loads of around 50,
CPU at 85% user, 15% system), lots of disk and network IO, basically
doing a lot of jpg->proprietary image conversions, then storing them
in the DB.) It had "come down" off this load, and was doing the same
thing + a lot of reading other images from the db when it hung.
I hope I've provided enough information.

Now this ksymoops was run well after the reboot--the -k and -l options I
passed were the closest in time prior to the crash.

"On two occasions, I have been asked [by members of Parliament], 'Pray,
Mr. Babbage, if you put into the machine wrong figures, will the right
answers come out?' I am not able to rightly apprehend the kind of confusion
of ideas that could provoke such a question." -- Charles Babbage
