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. > >> bug - kernel BUG at mm/rmap.c:725! .

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. > > Christian. > -- > BOFH excuse #102: > > Power company testing new voltage spike (creation) equipment > -- Best regards, [COOLCOLD-RIPN]
