Subject Re: java.lang.OutOfMemoryError: unable to create new native thread on AMQ 5.0

Could you try updating your activemq startup script so that instead of:
ACTIVEMQ_OPTS="-Xmx512M -Dorg.apache.activemq.UseDedicatedTaskRunner=true"
it reads as:
ACTIVEMQ_OPTS="-Xmx512M -Dorg.apache.activemq.UseDedicatedTaskRunner=false"

I think that should help with your thread usage issues.
