[EP-tech] Upload by URL floods /tmp

Temp file management varies; RHEL/Fedora have been deleting temp files for a long time, Debian hasn?t ever gone that route.

RHEL automatically runs tmpwatch


The equivalent on Debian appears to be tmp reaper; though considering it hasn?t had an update in 8 years it seems a ?buyer beware? situation.


I suggest systems-tmpfiles may be a better management mechanism for newer systems, and may be directly applicable to Yuri?s comment below


On a related note, I?ve just discovered that eprints calls wget directly, which I wasn?t expecting.

Also uploading can fill the "apache" tmp (this is debian, eprints 3.3.15):
