[Samba] Finished print jobs are piling up on windows clients

[samba at barendse.to]

Printing from windows clients to Samba through cups works perfectly but 
old (finished) print jobs are piling up in the print queue for the 
printer on the client side.

I never had this problem with the clients when the server was running 
RedHat 6.2 with Samba 2.2.8 and LPD. The server has
been replaced with a server running a RedHat Enterprise Linux rebuild 
(TaoLinux). The Samba version is 3.0.9

I already checked my cups files and had delete print jobs enabled from 
the start, also when I log into cups I don't see any printjobs.

I appears as if the jobs themselves aren't there anymore, if I restart a 
job nothing happens. I guess it's just some log lines (files)
that are kept in /var/cache/samba/printing

Any ideas why this is happening and how I can stop this? I don;t want all 
this old stuff.... Deleting the file for the corresponding printer seems 
to work but it's not an elegant solution.

Googling around didn't get me anywhere but it must be a known problem, I 
noticed this on 2 servers already

Thanks!!
