Title:
Sometimes system works too slow
Status in “linux” package in Ubuntu:
Expired
Bug description:
Bug starts to show up after last kernel update (3.8.0.21.37).
Sometimes system works very slow. 'top' command shows that many
processes produces 40-50% CPU loading. Processes every time are
different. Once udevd daemon produced 70% CPU loading and even 'ps'
command freezed when it's output was on udevd. java (tomcat, I think)
and xorg produces over 100% thery often. CPU cooler during this works
on maximum frequency and doesn't stop. CPU temperature increases to
60-65C.
After reboot everything works fine. Now summary CPU loading less then
10%, temperature - 40-45C. In spite of I have several hard programs
(eclipse, chrome, thunderbird and other) launched.
