Hi Don, For what I see from the system monitoring screen, the sems thread was removed when a caller hang up but the main sems threads are still running and growing in size. When the size reach 2GB, I can see pthread_create error 11. Size will only shrink when I restart sems but all my calls would have to be terminated abruptly. I'm not familiar with ethereal in linux, is there an easier way to solve this, like sample codes that I can use in the script? I have increased the RAM size to 1GB but it didn't help much. Sems just couldn't take more than 10 calls together running for more than 2hrs. Any advice is greatly appreciated. Thanks.

How can I check using commands that the thread is still in session? What are the commands in the scripts that close the rtp session? Please advice.

Look at the media streams with ethereal. Look closely at call disconnect. Be sure all threads are closed. don -------------- Original message from "Nicky" <nicky(a)caliber.com.sg>sg>: -------------- Dear All, I am having a serious problem, my thread memory size is growing to up to 2GB which applies to SEMS, SER and Mysqld thread. Please help. I am testing with about 10 people calling in at the same time. What shall I do? :( Nicky ----- Original Message ----- From: Nicky To: serusers(a)lists.iptel.org ; sems(a)lists.iptel.org Sent: Saturday, October 29, 2005 11:44 AM Subject: pthread create failed with code 11 Hi Support, I have experienced this error, please advice what can be the caused.
