Linux : SpamAssassin high CPU usage, keep flipping between running and zombie state

By | September 8, 2012

You may notice those symptoms after updating SpamAssassin :

High CPU usage
spamd keep flipping between “running” and “zombie” state

This probably mean your SpamAssassin installation is missing rule set configuration files. To resolve this issue, simply try running :

sa-update

Since this should have been automatically done at the installation or upgrade, you’ll probably end up with this error message :

channel: no ‘mirrors.updates.spamassassin.org’ record found, channel failed

There is probably a DNS issue on your server, try changing your resolver configuration file (/etc/resolv.conf) and run the command again.
