Many cache hits before message finally delivered

I am having an odd problem were simple messages seemingly at random take
a very long time to deliver.  Most others, deliver right away. A little
checking reveals that they are getting scanned for viruses multiple
times.  For example:

[root at mail etc]# grep Nov\ 30 /var/log/maillog|grep 98A1140460 |grep
SpamAssassin\ cache
Nov 30 08:55:29 mail MailScanner[27405]: SpamAssassin cache hit for

This ran about 500 times before the requeue finally took effect.  Any
ideas as to what can cause this?  I just updated clamav, but that does
not seem to help.  Below are the appropriate package versions.  Thanks
for any help in advance.
