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

[Andres]

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 at 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 at 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 at 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.
