Thread Count Reached - Causing System Failure

Hi Experts,

System Details: SAP PO 7.4 Single stack , single application server , 2 database servers and a heap size of 4096 MB.

Issue: The thread count on the server keeps growing whenever messages are processed but never comes down (even after the system is not processing a lot of messages) Eventually, the maximum number of threads is reached and system stops working until a restart.

Most of our interfaces deal with JMS and Idoc scenarios. The system has been functioning well until a recent release where new interfaces were added (more JMS/Idoc and couple of receiver JDBC scenarios). The CPU utilization and the memory used seem very much ok.

Have any of you also faced a similar situation before and how was that handled? Any pointers would be highly appreciated.

Thank you,
