Programmer was editing some scripts and reported he had messages in
console (actually the same messages as in the log), server was unable
to do usual work - LA becomes too high, so it was rebooted ( not
resetted ). After reboot server continued to work fine. Now I'm
figuring out what happened.

Machine was not rock solid - got occasional hangs once or two a month,
but without any records in logs and as there is no IPKVM, so i can't
say were something like kernel panic on console or not. Rephrasing
question - is this 'Kernel BUG' looking like bug or more than hardware
problem.
Memtest was not done yet though is planned when other machine will be rented.
