as far as i remember, the crash happened right after I started some 
request on the webserver, that is, only reading from the gluster. I've 
seen it happen radomly yesterday, I had the impression that it mostly 
happened when I relatively quick re-mounted the gluster volume. If I 
waited a  bit after a umount, it seemed not to happened. Sorry, not 
very precise :-( I will have look for the backtraces, if they differ I 
shall send them.


The undefined symbol happens immediately when trying to start nginx like 
shown.


Cheers, Sascha
