scheduler not responding!

When gnome is started up, the eggcups utility uses ~10% of the CPU time constantly, plus 90-95% of the network is being taken up.  End up having to kill it.

Viewing the error log at http://localhost:631/admin/log/error_log nothing appears to indicate any sort of problem that stands out at me.  Also turned on "Save debugging information for troubleshooting", restarted cupsd, nothing stands out again.

Are you by any chance perusing your old CUPS config files for the new
version? Did you remove and/or inspect /etc/cups/cupsd.conf,  /etc/cups/client.conf, your users' ~/.cupsrc, ~/.cups/client.conf files (watch for "ServerName" entries, and the IPP_Port ("Listen" or "Port" entries.).

Also, you may want to look into /etc/cups/printers.conf and /etc/cups/lpoptions, and your users' ~/.lpoptions files (from 1.1 to 1.2 CUPS has gained a few more and new options, and you'll not be using them if the old config files are still utilized).
