I understand. But I don't have anything to do, except hoping that
server will not crash, because with monitor in my situation system
gets frozen under normal load.

And 100 K of messages is not a reason for OOM. Dumping these messages
will be an OOM, error logger is the main reason to bring down VM.


By the way, have you seen my previous claim about non-atomic process startup?
Using supervisor  {error, {already_started,Pid}} feature is also not
100% unreliable because of race condition.
