Hello Stevica,

your system is oopsing while running rsync.
Is panic (and rebooting) enabled in /proc/sys/kernel/panic_on_oops and /proc/sys/kernel/panic?

Unfortunately linux does not have native crashdump capability, but there are utilities like lkcd (http://lkcd.sourceforge.net) which you might find useful.

nice evening,
Martin Hudec

Hello,

I have several Sun Fire X4200 servers and they are all running
smoothly on Gentoo except one. It constantly fail with error bellow.
At first I thought that it have a bad memory, so I run memtest and it
all passed. Then I thought it is firmware on my raid card, so I
upgraded firmware but it didn't help. I have 64 bit kernel. Anybody
have some more idea?

TNX a lot.
