[Samba] Thousands of TIME_WAIT connections with CUPS?

[Adam Nielsen]

Hi all,

For some reason I'm getting thousands of hanging TCP connections on our
server which appear to be caused by Samba sending print jobs to CUPS (or
I assume so as nothing else on the machine uses CUPS.)

These connections are starting to cause problems (programs monitoring
connections start breaking because it takes many seconds for them to
scan through the full list) so if anyone has any ideas how to rid the
system of these connections I'd be very appreciative!
