I deployed the bpel process in JBOSS AS in SOA Platform and it works fine.
But, when I tried to check for load testing using SOAP UI.
its stops with OutOfMemoryError as shown below.

java.lang.OutOfMemoryError: unable to create new native thread
Its a simple process flow which calculates ((a+b) * (a-b))^2. using web service which executes in remote server. Add, Subtract, Multiply and Square are independent services.

How to fix this?
In short, you face the “java.lang.OutOfMemoryError: Unable to create new native thread” whenever JVM is asking a new thread from the OS. Whenever the underlying OS cannot allocate a new native thread, this OutOfMemoryError will be thrown. The exact limit for native threads is platform dependent.
More often than not, the limits on new native threads hit by the OutOfMemoryError indicate a programming error. When your application is spawning thousands of threads then chances are that something has gone terribly wrong – there are not many applications out there which would benefit from such a vast amount of threads.
