[rabbitmq-discuss] rabbitmqctl often hangs at the end of a query, e.g., list_queues, for a good 60 seconds or more (Windows 7)

So sometimes just running 'rabbitmqctl', with no args, displays the help 
message and then hangs for 60s+ before terminating?

How easy is it to reproduce this behaviour?

It is certainly very strange behaviour, and not something we have ever 
seen before.

Btw, is the machine running Windows natively or virtualised?

Do you have a second machine on which to repeat the experiment?

ok. Do you by any chance have %RABBITMQ_CTL_ERL_ARGS% set to anything? 
Or any other %RABBITMQ_*% env vars? Your previous post 
indicates that at the very least you must have set %RABBITMQ_NODENAME%, 
since the status report is for a node other than 'rabbit'.

Also, do you really get a whole bunch of "PROGRESS REPORT" messages when 
running rabbitmqctl, as indicated by that post?
