PrivateTmp Strangeness — apachectl v/s systemctl

This is a very strange problem — we had a web server upgraded recently. We use “sudo apachectl start” to bring up the server since the server is maintained by a dedicated Unix support team, and the site worked fine. Until … Sunday morning after the log rotation. Then Box Spout was unable to access the XML data for an Excel file to compress it. Lots of errors:

The postupdate script is “systemctl reload httpd.service” — so not exactly the same thing we used to launch the service originally. But I’ve never seen differing behavior between apachectl and systemctl started HTTPD instances. Quick/dirty solution is to disable PrivateTmp, but I’m hoping to be able to isolate why exactly the postupdate script appears to break the service’s access to the private tmp space.
