Have a cluster (an independent cluster from the beam blocking issues reported earlier) which sometimes crashes on traffic spikes, with absolutely nothing in the logs. Apport does a crash dump, but nothing in syslog or anywhere. How can we diagnose this better?
If the Erlang VM exits abnormally it will usually at least print
something to stderr. So is anything in /var/log/rabbitmq/startup_err or
/var/log/rabbitmq/startup_log? If not I'm not sure what can be done.
