question on exitcode provided by status() method of Win32::Job

[stevehs17]

I have a question on the Perl module in CPAN, Win32::Job. I'm using the module to impose a timeout on a script I want to run.

My question is this. In the code in the function below, I check the value of the exitcode returned by the spawned script (see the line " $state = $rs->{$pid}{exitcode};"), which the spawned script explicitly sets (when it can).

However, in come cases, I get 13 as a value for the exitcode returned by the spawned script, which isn't one of the values I return from the spawned script. In those cases, the spawned script seems to have been aborted, though I can't always tell why. (I should mention that I'm using the script for monitoring a complicated system that has a lot going on, so it's not altogether surprising that the spawned script should run into problems from time to time - though I'd like to know what they are.)

I've gone through the documentation for the Win32::Job on CPAN, and I've done some Google searches and searches on this site, and I haven't been able to figure out what a 13 returned as an exitcode means. Can you tell me what it means, or, at least, where I can look to find this out?

Thanks, Steven
