Hello.
I have further news on my question - it's probably not Apache-related.
At this time the issue appears to be NFS file locking. The NFS server
where the files are stored was also upgraded and the mount options on
the web servers were changed slightly. Too many upgrades and changes
all at once. Not the way I usually operate.

All,
I have a Perl-CGI-based website that's been running on Debian/Apache
since at last Squeeze. The transition from Apache 2.2 to Apache 2.4
caused my organization some considerable heartache so we're just
finally getting to Buster.
Some of the Perl CGI scripts for this site, running with suexec,
manipulate a small set of files/directories in a specific user
directory. I had adjusted the site to run on Jessie-backports on one
server and used it that way for about a year and the file manipulation
was working fine - just like it always did.
Now that I have migrated to stretech-backports, the CGI-scripts that
manipulate the user files have stopped working - they just hang until
I get a 504 error. The Apache config and the site content were not
changed in the course of the upgrade. Since both Jessie and Stretch
run the same major release of Apache (2.4) I'm perplexed as to what
might have caused this.
My question: Is there anything that changed between these two Apache
versions or between these two Debian/Linux versions - a security
related policy change or a capability set change - that could inhibit
this kind of file I/O? And if there is, how do I re-enable this
capability?
Thanks.
-Dave
