Whilst not being a bug per se, it is annoying behaviour when rabbitmqctl 'sits there' for quite some time.<br>

<br>
How long is 'quite some time'?<br>
<br>
And what rabbitmqctl command were you trying to run? list_queues (as per the subject line)? If so, how many queues did you have at the time?<br>
<br>
And when you say (in the subject line) that rabbitmqctl hangs *at the end* of a query, do you mean it displays the results and *then* hangs?<br>

Interestingly enough, it does not accept <CTRL>C either.<br>

I'll have to find a Windows machine to try to reproduce that.<br>
<br>
Are you running the standard rabbitmqctl.bat script? In the other thread you posted some rabbitmqctl output which contained progress log information, which is not something we see in testing and for which the most plausible explanation is that some additional options have been passed to the erl executable.<br>

This wait is only encountered when activity is going on with<br>
RabbitMQ, no matter what it is.<br>

<br>
So this only happens when rabbit is really busy?<br>
<br>
Rabbit does prioritise handling of rabbitmqctl processing over most other tasks, but when the server is under heavy load it can still take some time to handle these requests. There is not much we can do about that really, since we wouldn't want to stop message processing altogether.<br>
