[rabbitmq-discuss] Silent crashes, and "killed by ABRT signal"

[Emile Joubert]

It looks like the out-of-memory killer killed the Erlang VM because the
OS was under memory pressure.

Not having any swapspace won't help.

It is possible to configure how the kernel deals with low memory in
overcommited situations. You should also configure some swapspace. If
you have any other services on the same OS that use alot of RAM then try
moving them to a different server.
