i can't run it so often, because to run it i think i have to unmount my 
filesystem. and of course this means longer downtime for my users, which 
for now i just can't do.

Maybe there is some kind of bug with this situation, because i forgot to 
tell you one thing: i have one more XFS partition that is inside this 
one big XFS partition.

its in fstab like this:
/var/eaccelerator      /eaccelerator   xfs     loop    0       0

and i did /var/eaccelerator with dd ( dd if=/dev/zero 
of=/var/eaccelerator ) with size of 1GB.

i deleted it for test purposes, and it didnt crash yet (but that doesnt 
mean anything, there were already times of 5 and more days working 
without crash and then suddenly it was happening)

so, does this loop partition can have anything to do ?

i will run xfs_check in a few days, unless there is a way to run it on 
mounted partition without the risk of wrong corruption reports
