The Erlang VM crashed because the OS could not allocate 1571344 bytes of
memory, and it doesn't look like the Erlang VM was using much memory
when it crashed. Do you have any other services running on the same
server? That is not recommended.

No, there is no limit. RabbitMQ expects to be able to use all the RAM in
the server. You can control how soon memory-conserving strategies are
applied with the memory high watermark setting. See
