Hi Folks,

I'm running a non-exit relay (v0.4.2.7) on OpenBSD 6.7. The amount of files within "/var/tor/diff-cache" is steadily increasing. Up to almost 6G fulfilling the /var partition to the max.

Is this an expected behavior? I there any solution to overcome it?

No, not expected at all.

Quickly glancing at an OpenBSD relay, I see ~250 files about ~500K in size.

Do you have a lot more files, or are they larger?

Definitely not expected behavior. Tor maintains a bunch of files there, and they can grow to take up a huge amount of space, but huge should be on the order of a few hundred megabytes. In particular, it should be automatically deleting files that are old enough to be unlikely to be used in practice.

I wonder if your OS is interfering with the deletion process somehow, like with an apparmor equivalent?

Or, has your clock changed in a significant way? What are the timestamps on the files?

Each file should be around 500KBytes to 1MByte ish, so if any of the files are way way bigger than this, that's good info too.

I do have 256 files, each 0.5 MB in size, the oldest is 24 hours old. So a retention seems not to work at your system.
