Thank you.
I checked the logs but the information was not clear to me.

I add the log of two different crashes. I will do an upgrade to 
glusterFS 6 in some weeks. Actually I cannot interrupt user activity on 
these servers since we are in the middle of the uni-semester.

If these logfiles reveal something interesting to you, would be nice to 
get a hint.


ol-data-client-2. Client process will keep trying to connect to glusterd 
until brick's port is available
