Public bug reported:
Binary package hint: clamav
# apt-cache policy clamav-daemon
clamav-daemon:
Installed: 0.96.3+dfsg-2ubuntu1.0.10.04.2
Candidate: 0.96.3+dfsg-2ubuntu1.0.10.04.2
Since the security update of clamav, the daemon takes multiple minutes
to load its virus database, and is causing random timeouts for users of
the unix socket (in my case, mimedefang), triggering repeated 400-series
email temp-fails each time freshclam issues a reload request.
strace just shows it slowly allocating memory and not doing much else.
Logs don't seem to help:

its socket.
