OutOfMemoryError: unable to create new native thread
Hi,
I'm currently load testing the native REST Api of activemq on our hardware.
I'm using pylot to generate several users.
Some time into the test i start to get:
WARN | Error for /rest/message/FOO/BAR

What causes the activemq to generate several thousand threads for my few
users?
I allready tried to use dedicatedTaskRunner=false in my broker conf. There
was no effect.
Greetings,
Alexander

Re: OutOfMemoryError: unable to create new native thread
Posted by Jeremy Levy <je...@gmail.com>.
*java.lang.OutOfMemoryError: unable to create new native thread*
Generally means that there isn't enough free memory for the OS to create a
new thread. I would suggest freeing up memory on the machine or REDUCING
the heap size of the JVM.
