Clamav not starting

[pavera]

I rebooted my server today for the first time in I dunno... 8 months.

Upon reboot, the server status reports that antivirus is not started, I have 82 mails in the deferred queue. The error there complains about not being able to connect to clamd on port 3310.

a ps aux | grep clamd reports:
zimbra 3877 82.4 1.6 18944 12772 ? Rs 21:13 0:30 /opt/zimbra/clamav/sbin/clamd --config-file /opt/zimbra/conf/clamd.conf

zmclamdctl start/stop seems to work normally, no errors are reported there

the clamd.log file reports "reading databases from /opt/zimbra/clamav/db"

It just seems to hang there. After a normal restart it will report how many signatures were loaded from the DB etc.. this does not happen

Top reports that the clamd process is using 100% of the CPU most of the time...

Further analysis of the logs shows that clamd is restarting every minute.

do I have corrupt db's? If so how to repair? Any other ideas/solutions?

What version are you running? If it's 4.5.6, please upgrade to 4.5.9.

In the process of performing said upgrade.
