Hi, I have been testing rabbitmq for a potential use at work. I am firing about 500 messages/sec (estimate) from 60 or so processes.  All starts well (I can see all the messages being pumped out, all going quickly) and after a few minutes rabbitmq halts with the error below - &#39;** gen_event handler rabbit_sasl_report_file_h crashed.

&#39;<br>(same error keeps occuring). <br><br>Infrastructure wise I have a simple queue setup with one consumer (erlang client)  with the producer a java client; sending very short messages<br>The box is running a single rabbitmq server process and is a quad core, 2 gig box<br>

<br>Things I have tried so far:<br>Increase the ulimit to 100,000+<br>Increase the number of consumers to 3 to try and take any load off the rabbitmq server<br>Use ERL_MAX_PORTS 10240 / ERL_MAX_ETS_TABLES 10240<br><br>Any help would be great,<br>

<br>thanks<br><br>Patrick<br><br>=ERROR REPORT==== 5-Aug-2009::01:00:42 ===
