Hi Tim,

I finally reproduced an instance where rabbitmq-server appears to hang.  Here's the the output of the command:
#  rabbitmqctl eval 'process_info(whereis(rabbit_channel_sup_sup)).'
Error: {badarg,[{erlang,process_info,[undefined],[]},
                {erl_eval,do_apply,6,[{file,"erl_eval.erl"},{line,572}]},
                {rpc,'-handle_call_call/6-fun-0-',5,
                     [{file,"rpc.erl"},{line,203}]}]}

Liz

If you can give me ssh access to the machine where the shutdown is hanging then I can do this for you, otherwise I'll write up a module you can compile and execute using escript and send it to you. I have actually started on that latter idea anyway, but it's getting a bit late now so I'll probably finish it off in the morning! :)

Actually come to think of it, we could check a couple of things briefly using rabbitmqctl first. Can you send the output of this please: rabbitmqctl eval 'process_info(whereis(rabbit_channel_sup_sup)).'
