Comment 3 for bug 1855199

Ran into this today. It is also very likely the problem for a few of the folks on this thread, though it was only ever diagnosed in a roundabout way (i.e. never pointed back the the systemd PrivateTmp feature): https://<email address hidden>/msg00302.html

Seems like moving the default to something like /openils/var/tmp/ as suggested (or even just /openils/tmp/) is a simple and sane path forward.
