Hello All,
Ive got an issue which I cant seem to get to grips with.
Setup is an Sun E450, 768MB RAM, single CPU, sendmail-8.12.3, BIND 9.2.0,
QPOPPER 4.0.3
I am getting ridiculous CPU load as per vmstat below. Load I expect on this
machine is from around 5k email boxes who of course will not be accessing it
all the same time.
Is there a way that I can view what is consuming so much CPU time, other
than ps and top
TOP reports available memory and the CPU colum in its output doesnt add up.
So something is consuming CPU time and I cant quite figure out what.
Any help is appreaciated
Thanks
Mark
