Have you checked if the clamd process has died? I've seen it die
sometimes after a freshclam update.
Anyway, I've recently changed this in milter-clamc for the next release:
! Accept the message in the event of an clamd socket error,
instead of temporaily rejecting the mail. Better to let
the mail keep flowing. Sometimes clamd disappears.

Possibly. Never thought of that. You try setting
about 64KB smaller than clamd's max size and see if milter-clamc is more
graceful when it knows to limit message size. Note that because of how
the sendmail / milter passes date, clamd-max-size is convert into max.
number of 64KB chunks rounded up. So if you specify clamd-max-size=32,
it would actual do 64KB.
