status query from smbd->cups server which has changed api.
Large site(s) upgrade from 3.0.10 to 3.0.25 (also tested 3.0.28) causes high cpu usage in cups; even when no one is printing. Cpu usage hovers around 20-50% usage with approximately 80+ printers.
Have changed some configuration options such as the following which lower load slightly.
lpq cache time = 900 #30
printcap cache time = 900
The cups access_log is also growing rapidly; approx 50 messages per a second. We have sent these to /dev/null for the time been.
Please investigate and fix.
This was caused by not having comment and description field set for printers; samba would query cups for the information instead of local database.
