BrowsePoll and lots of printers

> I´ve tried to raise the value for timeout to 3600 seconds, but its still removing the queues. Is there any way to tell CUPS not to remove queues due to timeout. The master server never removes the queues.

1. Change the browseinterval. That value is the one that creates the
load on the server. Set that to 1800 or more. And also have a pretty
high timeout.

2. Upgrade cups. There are perfomance problems with that amount of
printers in 1.1 series.
