MailScanner causing high cpu usage

Post by i_like_penguins »

I have a new install using the vmware image. 2cpu cores and 4gb ram. Mailscanner is using 80-100% cpu usage without any mail going through the system. The mail queues are empty. How do I figure out what is happening?

You'll need to use programs like "top" to find out what is sucking up the cpu and why.

the following programs are also helpful in finding out what's happening:
- atop
- vmstat
- iostat

Reboot fixed it. Which is strange for linux. I think it updated and maybe a watcher script could not find the mail scanner PID. what was happening was mailscanner was crashing or being restated every 3-5 seconds.
