I invoke 12 CLI commands from HPUX 11.31 to synchronize 12 clones within a cloneset.  About 1 out of 30 times I get a network timeout on one of the 12 commands.   Anybody know why?

A network error occurred while trying to connect: '172.20.50.4'.
Message : Error occurred because of time out

And it happened on ERP_PRD_C_MP85

Loooking at the events on the Service Processors, there are no errors.  Ultimately I went into Navisphere and just had the clone synchronize.   I probably could have also used the CLI command above to do it as well.   The question is

1)  Is there a limit to how many commands can be submitted in a row?   Should I put a sleep between the commands to slow the script down.

2)   Is this really a network error.   This usually occurs at 5:00 am when there is almost no network traffic.

3)   Any other thoughts as to why I am getting this issue.
