Solution

This is a known problem that has already been fixed in Imunify since version 6.4. To fix it, it is enough to update Imunify to the latest current release.

For earlier versions, and in situations where updating is not the appropriate option, the minidaemon process can be killed with the following command:

# kill $(ps aux | grep minidaemon-av | grep -v grep | awk '{ print $2 }')

Cause

Software issue DEF-19290 which is fixed in the 6.4 release. During the update minidaemon process with minidaemon-av.cfg stay running.
