reason for "magic" crashes.

[Wojciech Puchar]

i've got third crash third week in a row.

Every time in sunday after 18:00, every time with rsync process (which 
means rsync based backup that is done every day, not just in sunday!),

you may see a crash (viewed from KVM) at

what is important - syncing disk doesn't go on, system hangs here.

For 99% system is not overheating at sunday, but i will be 100% sure as i 
added ipmitool sensor logged from cron every 5 minutes.

Please give me an idea what to check.


There is nothing in cron that is done at sunday.

i don't run "periodic" stuff in /etc/crontab
