Subject Re: ava.lang.OutOfMemoryError: Failed to fork OS thread - 5.2.0 broker
Date Tue, 06 Oct 2009 22:00:47 GMT

Dan,

The message size is ~1500 bytes on average, 90% are 1100 bytes. The consumer
should be very fast, up to 1000 msg/sec for each consumer with 24 consumers
pulling from a single broker. The producers are not enqueueing anything near
that rate. Generally we are in the 50-100 msg/sec rate for all the producers
combined.

Our configuration is pretty much the stock config. The only real change we
have made is to turn off the dedicate task runner:
-Dorg.apache.activemq.UseDedicatedTaskRunner=false.

Thanks for your help, 
-Jimmy
