[rabbitmq-discuss] mnesia is overloaded

Sat Jul 10 15:47:34 BST 2010

I'm running some tests locally and I'm making a change and then just re-running the unit test, which fires up a bunch of listeners and starts dumping messages right away. Randomly, one part of my tests will hang. I noticed the following in the log file. Do I need to change some settings or something? I'm only sending several dozen messages at once...

=WARNING REPORT==== 10-Jul-2010::09:01:05 ===
Mnesia('rabbit at brisbins-mbp'): ** WARNING ** Mnesia is overloaded: {dump_log,
                                                                    time_threshold}

=WARNING REPORT==== 10-Jul-2010::09:01:05 ===
Mnesia('rabbit at brisbins-mbp'): ** WARNING ** Mnesia is overloaded: {dump_log,
                                                                    time_threshold}

It looks like one log message per sender (each in their own thread) and the first half of the test works but it has trouble sending responses back to the requestor, which is where it hangs.

I'm on OS X 10.6 with MacPorts-installed RabbitMQ 1.7.2 broker with the 1.8.0 client (though I did notice the same behaviour yesterday using 1.8.0 broker on Ubuntu...just didn't check the logs).

Thanks!
