Re: java.lang.OutOfMemoryError: unable to create new native thread

OS version:Red Hat Enterprise Linux AS release 3 (Taroon Update 3). What does the mxm mean?
The server is stable and os memory is very enough when running 300 users or 400 users.
OC4J_BI_Forms memory is very enough when running 300 users or 400 users.
We quried metalink about this case,but no solution for me. Therefore,We must rely on ourselves.
