Occasionally (after some amount uptime which I haven't measured yet), my /var/run/projectname directory will disappear along with the /var/run/projectname/gunicorn.sock file.
Rebooting brings it back as I do have it configured in tmpfiles.d:
d /var/run/projectname 0775 207 root -
The supervisord services recreate the .sock file at reboot, which is a Django gunicorn socket that nginx uses to deploy the app.
/usr/lib/tmpfiles.d/tmp.conf doesn't include /var/run and I don't have a tmpwatch job in /etc/cron.daily either. /var/spool/cron is empty and /etc/cron.* doesn't have a relevant job either.
Any ideas of what could be wiping this ...or how to audit it?
Note: This is not a duplicate of Folder disappearing from /var/run upon reboot with Ubuntu 12.04 because that question complains about the files disappearing after a reboot. My problem is when the system is still running.
