temp files not being processed - score=0 (UNCLASSIFIED)

I've had the "(not cached, score=0, required 5, autolearn=)" problem
several times myself. Typically restarting MailScanner fixed the
problem. Last time it happened, simply restarting didn't help so I
tried removing SpamAssassin.cache.db and the problem stopped. Can't say
for sure removing the cache was the fix, but worth a try.
BTW, is there something similar to db_verify that can be run on the
SpamAssassin cache to check for consistency?

<<ms.zxp>>
I have posted this problem before, but I have not found a solution, and
I really need the forum's help.
One of our MX servers is leaving files in
/var/spool/MailScanner/incoming/SpamAssassin-Temp. It appears that each
one being left is getting a 0 score.
I ran this by Julian recently, and he said he was at least the same
issue of files being left in that dir.
I added an entry in cron to remove them, but it is just cleaning up the
files leftover from a real problem:
1 * * * * /usr/bin/find
/var/spool/MailScanner/incoming/SpamAssassin-Temp -type f -mtime +1
-print | /usr/bin/xargs rm -f # delete leftover temp files
Here are the number of files in the for today and yesterday:
root at houmx05:/var/spool/MailScanner/incoming/SpamAssassin-Temp
# ls -la | grep -c ' Aug 19 '
2409
# ls -la | grep -c ' Aug 18 '
2135
Although not perfect, here is a count of 'score=0' lines from the
maillog for the respective days:
# zcat /var/log/maillog.1.gz | grep -c score=0
1221
# zcat /var/log/maillog.2.gz | grep -c score=0
1400
I have already lowered the MX priority of this server to try and receive
less email, but it's still delivering emails (not all) with a zero
score.
I have included MailScanner -v and an output from MailScanner --debug
--debug-sa as well (attached ms.zxp - rename to .zip to extract) as the
contents of the email. I saw one possible discrepancy in processing the
2nd email via the debug option where it did not end with 'I am
generating a hash using the input of'. The output show two emails being
processed. The last one was definitely spam, but was scored as 0 and
was left in the /var/spool/MailScanner/incoming/SpamAssassin-Temp dir.

Is there any more debug options I can use to figure this one out?
