Subject Re: java.lang.OutOfMemoryError: unable to create new native thread on AMQ 5.0
Date Thu, 15 May 2008 21:54:41 GMT


Hi Hiram,

We were having similar issue and  confirmed the following
(-Dorg.apache.activemq.UseDedicatedTaskRunner=false) works for us.

What are the implications of doing this ? 

Thanks
- Sridhar
