I can see same things in my logs. It's sendmail
8.12.10+clamd+clamav-milter v 0.70-rc on Solaris9 (sparc).
It happens only for few sender adresses (always the same),
other mail is accepted/rejected properly. And not necessarily for
big messages - it happens for small too. After enabling syslog
I found lines like below :

I've found in clamav-milter.c this "write failure to clamd"; it's in
clamfi_send() function, just after calling checkClamd(). It appears
like checking if clamd is alive ? But it is, next mail form another
sender is properly received...
Can't understand it, maybe Nigel could explain ?
