Apologies if this is a bit of a n00b question, but I haven't found the 
answer anywhere else:

Is there a way to see the number of lightweight Erlang processes 
currently in use by rabbitmq? We regularly run out of them, even with a 
higher-than-default number being specified (65535), and while I realise 
that there may be an underlying issue, it would still be very useful to 
monitor the usage.

Secondly, are there any guidlines re. the maximum recommended number of 
Erlang processes we should/could specify for a given machine spec (we're 
running on a RHEL server with 24GB RAM).

Note we're still running 1.7.2, not moved to 2.x yet.
