Figuring out what makes folders vanish

[madchaz]

Good day all,
I'm facing a bit of a head scratcher.

I have a ramdrive I dump short lived data in. The data is organished in folders.

However, if I have an empty folder, something deletes it and I can't for the life of me figure it out.

What I have done so far


1: Stop all scripts for my application and/or do a fresh reboot (app is started manually)
2: Use inotify to monitor the folder
3: use auditd to try and figure out what process deletes it.


Results:
1: folder still vanish
2: inotify does show the folder being created, then being deleted.
When I delete the folder intentionally, I get a DELETE_SELF followed by a DELETE event.
When it vanishes on it's own, I get a DELETE_SELF event followed by a DELETE event, just the same.
3: the logs for auditd show when I intentionally delete the folder.
NO activity when the folder vanishes.

Anyone as an idea where to look next?

This feels like it might be a good fit for dtrace to capture the PID and process name.
