Just an update here, the issue only came up once again on another system 
and I didn't have time for a couple of days to even save the collectl 
log file. I then increased the max number of rotated log files, but it 
didn't happen again ever since. So I don't have any logs about the state 
of the system at crash time so far.
However, I just got a captured file corruption:

Hmm, exactly 64 bytes of corrupted data, the file itself has a size of 
512MiB.

I'm going to export single disks from the controller to use it with 
md-raid6 as this allows to do parity checks and to identify bad disks.


Cheers,
Bernd
