Segmentation Violation

[George Simon]

No, we have a filePro program that is part of a process that scans records and checks them against other lists.
Here is what is happening as I understand it from our programmer (the following are his words):
-----------------------------------------------------------------------------------------------------------------------------------------------
1.       There is something happening that doesn't allow a scan process to complete (presumably a segmentation violation)
2.       The queue_manager sends files to the dropoff folder to send to the API processing system.
3.       The queue_manager waits a total of 10 seconds for a response transaction to return.
4.       If it doesn't return, it logs it and sends the next transaction in.

This is where we have the issue (point 4). We continue sending transactions while there maybe 32 zombie processes which
exhaust the filePro license.

What I've done.

1.       Increased the timer from 10 seconds to 45 seconds for a response transaction.
2.       Placed a wait to make sure the scan (of name and address) occurs. I know this is complete if there are lock files in the temp dir.
3.       If the temp files do not appear within 45 seconds, I (kill -9 $!) - thus killing the process 

I'm placing some finishing touches on it.  I hope for a clean batch tonight without the issue of over-licensing.

A SEGV means the program has already exited.

Well, to be more specific, in the case of filePro, filePro catches the 
SIGSEGV signal, does some quick cleanup, outputs "***segmentation 
violation", and then exits.

Are you saying this isn't the case on your system?
