I don't think it could be filesystem corruption problem, I fscked all the
partitions and they all seem okay. I also have 2 hard drives in gmirror
(RAID-1) and therefore I think this can not be faulty hard drives either.
I will check memory, though. I it is really difficult to test CPU, since
it is a HP ProLiant server, so it's difficult to try another CPU.

So I'll try these steps:

1. test memory with memtest;
2. take one of the RAID drives out and place it in another computer and
   try to run rdiff-backup on it.


Thanks,
Nejc
