Title:
cups 2.0.2-1 100% cpu usage
Status in cups package in Ubuntu:
Fix Released
Status in cups source package in Vivid:
Fix Released
Bug description:
upgraded from xubuntu 14.10 to 15.04 and now it uses cups 2.x
after every print cupsd starts using 100% cpu and don't close.
have to kill it every time with "sudo pkill cupsd"
printing still works fine
[Impact]
CUPS 2.0.x can suddenly take 100% CPU in certain situations, making
the system slow and producing fan noise.
[Test Case]
After printing a job cupsd takes 100% CPU. This does not occur for all
users, probably depends on queue type and on timing (computer/network
speed).
With the proposed package the problem does not occur any more.
[Regression Potential]
Very low. The patch is very simple.
