Postprocessor not checking if releases are passworded?

[rembo10]

Hey - not sure if this is a problem with my setup (because I remember it working before - but with a new install it doesn't seem to be). I have a ton of rows in my db with the 'UNKNOWN' status - and they never seem to get checked. It's been a few weeks so I don't think it's a matter of the backlog. My settings:
'process_rars': True,
'unrar_path': '/usr/bin/unrar',
'delete_spam': True,
'delete_passworded': True,
'delete_potentially_passworded': True,
'delete_bad_releases': True,
'delete_blacklisted_releases': True,

And unrar is installed at:
└> which unrar
/usr/bin/unrar

Not sure why it isn't processing these...... Let me know if you need more info
