There is a value in there called "CGI Timeout" that needs increasing.


Looks like this is what is causing my problems. Here is something I came across when I was looking at CGI script guidelines.

Please optimize your scripts relative to memory usage and <br />
CPU time. Our system automatically stops scripts that use too many system <br />
resources. <br />
<br />
Programming Limits: <br />
CPU : 6 seconds @ 100%<br />
Memory : 10240KB (10MB)<br />
Numerical Processes : 12


The reason the backup scripts were varying widely is that I have a random (within a range) wait programmed into the main loops of all the scripts.

I do this to insure that I don't get scripts executing in lock step hitting resources like a synchronized artillery barrage.

By making the process sleep for a random interval with a range (i.e. randomly between 3 and 15 seconds), I insure that even two simultaneous executions of the same script against different db tables do not synchronize.

In fact two executions of the same script against the same resource (for example a daily backup two days in a row) will take a different amounts of time to complete processing.

That solves the backup script anomaly.

As for the proof of concept scheduler I am thinking that it sometimes got further because of other scripts that were competing for resources at the time of execution.

In any case the limits set down are the ones I need to live with. At least now I know what is at play and can break up the processing accordingly.

Thanks for helping to solve this problem for me. Cool | :cool: I was at my wits end trying to understand what was going on.
