Subject Re: ActiveMQ : java.lang.OutOfMemoryError: unable to create new native thread
Date Tue, 17 Jul 2007 20:52:49 GMT

The number of threads is increasing constantly. 

Now I have. 

Live Theads 400. Daemon threads 388
Peak 401. Total started 814. 

Why is that?  I am sending and consuming message every minute by stomp
