Hi Serge,

We discussed two problems.

1)Can the process done swap out of do detection in pgrep?
  There is a doubtful mention in online help of pgrep.
2)There is the case that there is a process having same PID in a failover node.
  For example, this problem get up accidentally when an active node rebooted 
suddenly.

In conclusion...

1)Can detect the process done swap out of in pgrep.
  But when process became the zombie process, pgrep cannot detect it, but we 
decided not to consider
this.
2)When there was a PID file, we decided to perform the check of PID for a 
result of pgrep.
  And, the enforcement of kill decided to abolish it because there were not 
many meanings.

I revised the mistake of some patches which you offered.

There may be waste to this script.
Remove waste and I wish you include it in a development version.

Sorry...
This revision does not consider the contents of the other mailing lists that 
you discuss.
