Hi folks,
I've got a problem with my laptop that's recently occurred. The
processor usage gets stuck at 100%, and I can't work out why. If I look
at processes with top or htop, atd is the biggest user of the processor,
with about 20%. Adding up all the processes gives a rough total of
30%. No idea of where the other 70% is going, yet the total at the top
is 100%. Issuing the command
sudo service stop atd
almost immediately brings the total processor usage down to 2-18%. Then
issuing
sudo service start atd
takes it right back up to 100%
Any idea what atd is up to? How can I find out? I did get a disk space
warning the other day, but have freed up a load of space since.
Ubuntu 11.04, fully patched. No recent changes AFAIK apart from
installing patches regularly.
Any ideas?
Steve
