In RHEL, the CUPS "cupsd" process runs at 100% for more than 30 seconds
Issue
- The CUPS
cupsd
process runs at 100% for 30 seconds straight. - Using the web interface if we click "Show all jobs" the
cupsd
process will consume 100% of the CPU (one core out of four) for 260 seconds. - CUPS starts using more CPU resources when we access CUPS UI or use
lpstat
. - CUPS stops responding, usually after
lpstat
or similar command.
Environment
- Red Hat Enterprise Linux (RHEL) 5, 6, and 7
- Common Unix Printing System (CUPS) 1.3.7, 1.4.2, and 1.6.3
