Is there any way to tell if a SER Child is Blocked? Any debug command or log message available? Thanks, -- Andres Network Admin http://www.telesip.net

Thanks Klaus, I tried it on our lab with a ser.cfg that called an exec program that looped forever in order to block the child. This is the result with 4 children defined: Before the first Registration: [root@maui2 bin]# ps -Al | grep ser 1 S 0 15550 1 2 85 0 - 11532 pause ? 00:00:00 ser 1 S 0 15553 15550 0 85 0 - 11532 pipe_w ? 00:00:00 ser 1 S 0 15566 15550 0 80 0 - 11532 schedu ? 00:00:00 ser After the 4 Children get locked up: [root@maui2 bin]# ps -Al | grep ser 1 S 0 15550 1 0 85 0 - 11532 pause ? 00:00:00 ser 1 S 0 15553 15550 0 85 0 - 11532 pipe_w ? 00:00:00 ser 1 S 0 15558 15550 0 75 0 - 11533 wait4 ? 00:00:00 ser 1 S 0 15559 15550 0 77 0 - 11533 wait4 ? 00:00:00 ser 1 S 0 15560 15550 0 77 0 - 11533 wait4 ? 00:00:00 ser 1 S 0 15561 15550 0 77 0 - 11533 wait4 ? 00:00:00 ser 1 S 0 15566 15550 0 75 0 - 11532 schedu ? 00:00:00 ser And Finally After releasing them: [root@maui2 bin]# ps -Al | grep ser 1 S 0 15550 1 0 85 0 - 11532 pause ? 00:00:00 ser 1 S 0 15553 15550 0 75 0 - 11532 pipe_w ? 00:00:00 ser 1 S 0 15558 15550 0 78 0 - 11532 schedu ? 00:00:00 ser 1 S 0 15559 15550 0 75 0 - 11532 schedu ? 00:00:00 ser 1 S 0 15560 15550 0 75 0 - 11532 schedu ? 00:00:03 ser 1 S 0 15561 15550 0 75 0 - 11532 schedu ? 00:00:00 ser 1 S 0 15566 15550 0 75 0 - 11532 schedu ? 00:00:00 ser So the key here is to spot the children with "wait4" and that tells us they are blocked. Thanks for the great suggestion! Andres. Klaus Darilion wrote:
