after recent update to 0.91.1 we started to get clamav-milter timeouts
for some small text messages:

sm-mta[2821]: [ID 801593 mail.error] l7112wKD002821: Milter (clmilter): 
timeout during data read
sm-mta[2821]: [ID 801593 mail.info] l7112wKD002821: Milter (clmilter): 
to error state
sm-mta[2821]: [ID 801593 mail.info] l7112wKD002821: to=<***>, 
delay=00:15:00, pri=92336, stat=Please try again later

eventually after being deferred several times the message will go 
through and the problem can be reproducable (but not always).
i tried to truss clamav-milter when it hangs, but it did not get me 
anywhere.

no messages in clamavlog file. current times in sendmail.cf are pretty 
long (to accomodate 75MB messages):

T=C:5m;S:4m;R:15m;E:16m

one of the messages which caused clama-milter to go to coma had
a relatively wrong line:

^begin  quoting

which would trigger an error "LibClamAV Error: Message is not in 
uuencoded format". more on that in:

https://wwws.clamav.net/bugzilla/show_bug.cgi?id=586

other messages don't have any obviously wrong lines, but usually have 
several included/forwarded messages with From lines.

downgrading to 0.91 fixed this problem for several days and now it 
started to happen again. restarting clamav-milter didn't fix it even 
temporary.

any idea what might cause that?
