Many thanks for these. The Erlang VM gets very upset when it runs out of
available file descriptors. The safest thing to do is just to massively
raise the limit through ulimit. That said, we do have some plans to be
able to artificially limit the number of FDs Rabbit is using to a little
less than the actual limit. This would allow Rabbit to successfully
refuse new connections when it gets to this artificial limit, and leave
enough FDs around for the VM to continue with.
