Hi,
We are running an intranet application using JSP/Java and
Tomcat Server. We are getting the following error.
Mar 12, 2007 8:02:48 AM org.apache.tomcat.util.threads.ThreadPool$ControlRunnable run
SEVERE: Caught exception (java.lang.OutOfMemoryError: unable to create new native
thread) executing org.apache.tomcat.util.net.TcpWorkerThread@e60a94, terminating thread
Particularly we are getting this error when the Current Thread equals the Busy thread count in manager. And when it reaches the max thread, the server crashes. We even tried to increase size of the heap and also thread size. We could not identify why the server is crashing.
Connection Pool settings:
Maximum active connections: 10
Max idle connection : 4
Thread Settings
Max threads : 53
Min spare threads : 5
Max spare threads : 15
Tomcat is running on HP-UX server. It supports only 64 threads per process. I've even tried setting the heap size to 1gb and tried analyzing the heap using verbosegc option.But nothing helped.
Please help.
Regards,
Firvin
