Apparently for months now, some process has been creating an empty .svg file in /tmp every minute and leaving it there. I now have 43,000 of these 262 byte files accumulated. I could just periodically delete them, but it'd be great if I could find the cause and even prevent it.
Does anyone know what this might be, or how to find out? I'd rather not try to figure out how to remount /tmp on a separate filesystem, like in this answer, and auditctl hasn't worked for me. Short of these methods, am I left with running lsof in a loop? It hasn't yielded anything yet.
Here's the contents of the .svg (it's always the same):
$ cat /tmp/tmpuo80js2t.svg <?xml version="1.0" encoding="UTF-8" standalone="no"?><svg id="empty" xmlns="http://www.w3.org/2000/svg" height="22" width="1" version="1.0" xmlns:xlink="http://www.w3.org/1999/xlink"></svg>
Update: The filename pattern is
/tmp/tmp????????.svg. Some examples:
/tmp/tmpsxzk1ktl.svg /tmp/tmpti2by97z.svg /tmp/tmp0woym_0_.svg
