Hi,
I assume you are running the milter on the same machine as clamd and
letting them talk over a unix socket.

It is very likely that clamd got tired of waiting and closed the connection.
Try increasing the ***Timeout values in clamd.conf.
Or try decreasing MaxFileSize in the clamav-milter.conf.

At any rate, make sure you are not heavily IO bound on the milter
machine and that the network flow between the sendmail and the milter
machines is fast and not congested. If that's the case you may need to
rethink your setup as it's way underspec'd.


Having said that, please note that rare transient errors occurring
during peak times are nicely handled by the SMTP protocol and are
generally not considered a big issue.

Cheers,
