It looks like erlang was trying to allocate 5 gigs of RAM, and failed.
This could have happened during garbage collection, but only
if a single erlang process was using all the memory.

Do you have a single large queue?
Are you sure that the queue had reasonable size during the crash?
Maybe all the consumers had died and rabbit just ran out of memory?
