Thanks for responding, BrowserUk, this is really helpful.

$lockfile is definitely not a shared variable

Yes, I did redact the server and share names. The boss requires that we continue to redact this type of information for security reasons. I can tell you that the server name is the same in every instance, but the share name has been different each time. Here are all of the examples I have in my log files:

20150509-stderr.log:Thread 6 terminated abnormally: Failed to open \\<
+i>PRODSERVERA</i>\<i>BEYC</i>\INQUEUE\loadqueue.lck: Invalid argument
+ at service.plx line 596.
20150523-stderr.log:Thread 7 terminated abnormally: Failed to open \\<
+i>PRODSERVERA</i>\<i>FRT4</i>\INQUEUE\loadqueue.lck: Invalid argument
+ at service.plx line 596.
20150704-stderr.log:Thread 10 terminated abnormally: Failed to open \\
+<i>PRODSERVERA</i>\<i>JPGE</i>\INQUEUE\loadqueue.lck: Invalid argumen
+t at service.plx line 596.

The logging is being handled by a Thread::Queue (actually by two - one for STDOUT and one for STDERR), so all of the log entries are in chronological order, although I don't capture specific file system activity at the moment.

In each case, the pattern around what happened is different. In the case of BEYC, the faulting thread loaded files for BEYC, then did a whole bunch of other recipients for the next 12 hours, then crashed on the very next BEYC file to come in. For FRT4, it loaded a bunch of files, with the last file being loaded using a library call and crashing out on the very next file that needed to load. For JPGE, it again loaded a bunch of files successfully, but the last file loaded was passed out to a new Perl instance in a system call before crashing on the next file.
