Same issue here (debian 6.06, airtime 2.2.0-2).
First after restarting of server comes uploaded files from tmp/plupload into watched folder.
Bump, have the same issue in 2.3.0 Ubuntu 12.0.4. LTS when i upload files they arrive in /tmp/plupload but never merged into the library. I have tried service airtime-media-monitor restart, does nothing.
the output from airtime-check
