Re: [Serusers] How to Tell if a SER Child is Blocked

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!

Is there any way to tell if a SER Child is Blocked? Any debug command or log message available?

Thanks,

                                     ^^^^^^^^

I guess this will show the status of the threads
