Some AV tests taking very long time

[Jānis]

Hi!

I have a strange problem with amavis:

some tests are taking extreeemly long time:

Jul  6 23:48:52 server.fqdn /usr/sbin/amavisd-new[17773]: (17773-03)

(especially - AV-scan-2: 111634 (93%)

and - as a result - sending server does not receive timely acceptance  
and interrupts transmission. The message is sent repeatedly over and  
over

Jul  6 23:48:52 server.fqdn /usr/sbin/amavisd-new[17773]: (17773-03)  
SMTP session over, timer stopped
Jul  6 23:48:52 server.fqdn /usr/sbin/amavisd-new[17773]: (17773-03)  
ESMTP: notice: client broke the connection without a QUIT ()

What this AV-scan-2 represents? may be it is some problem with clamav  
(0.101.2) - on servers with older one I do not observe such delays.
