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.
