Hi Christian,

yes, a dump should be generated, as long as the server working directory (as 
specified with parameter) is writable for this user, and the ulimits allows 
it too. The ulimit is set if you enable coredumps in /etc/default/openser.

Perhaps this error causes a SIG11 in the libmysql? This whole cluster stuff 
don't seem that stable on errors sometimes, at least my short google research 
suggest this. Normal driver errors don't causes this problems, i observed 
this too.
