>Description:
When the database directory of ClamAV is locked, clamav is terminating.

It seems to me, that this is because of freshclam, which is not able to reach any listed mirrors at this moment.

IMO: ClamAV should not force a reload, if the directory is locked and ClamAV can not proceed because of this reason. (Why force a reload, which will fail?)

Looks like a "negative feature" to me.      

/var/log/clamav/clamd.log

Seems, that the directory is stil locked by freshclam, which had problems to reach any mirror at this time:

Update failed. Your network may be down or none of the mirrors listed in freshclam.conf is working. Check http://www.clamav.net/support/mirror-problem for possible reasons.

I'm useing ClamAV from ports. I haven't seen something releated in /usr/ports/UPDATING

# pkg_info | grep clamav
clamav-0.92.1_1     Command line virus scanner written entirely in C

I'm contacting FreeBSD, not ClamAV because of:
"Please do not report any bug affecting software derived from ClamAV and distributed by a third party (i.e. ports we do not maintain directly) because we have no control over them. Contact their developers instead." (http://www.clamav.org/bugs/)

Status critical because virus scanning/delivery of email stops working...
