So it's me again. I am a little desperate by now. My guess to blame the
erlang-mysql interface was not successful. I recompiled it but the
server kept crashing irregularly. We finally did our last shot to blame
the virtual machine and/or hardware the server was running on. So we
rebuild the whole server using FreeBSD 7.2-RELEASE-p3 and erlang,
ejabberd, mysql from the current ports tree.
After running for a few ours the same behavior started all over. Server
crashing with erlang dump no logfiles.
We assume there might be a bug in erlang-mysql vs. the latest mysql-5.0
I'd absolutely appreciate every help or suggestion what to do or how to
debug. The server is an privately run machine but has about 500 active
users who are getting upset and we don't know what to do and what to
look for anymore.
P.S.: We are not sure - but their might be an correlation between the
latest mysql-50 release and the start of the odd behavior.
