[cobalt-users] high usage of in.qpopper

["kajan" <kajan@xxxxxxxxxxxxxx>]

I have a raq3i server which is always overloaded in the working hours.
I found out that in.qpopper is using more resources.
I have 70 mail customers with 850 users & 3 web customers.
I get 20000 to 25000 pop logins a day.

Following is the result of "top" command.

Is my server overloaded. Or is  in.qpopper misbehaving?
Will rebuilding the source code of in.qpopper help?

Thanks in advance.
