Milter-greylist

Noticed today some unusual log entries from milter-greylist 1.4 and
sendmail.

It appears that milter-greylist is writing entries to the log file out
of order.  It also appears that the milter is timing out per the entries
that sendmail is logging.  

Example below:

Jul 14 09:05:11 webserver sendmail[17140]: i6ED4vKP017140: Milter
(greylist): timeout before data read
Jul 14 09:05:17 webserver sendmail[17140]: i6ED4vKP017140: Milter
(greylist): to error state
Jul 14 09:05:02 webserver milter-greylist: i6ED4vKP017140: addr
218.165.213.230 from <roughshod0@...> to
<aguirre@...> delayed for 00:02:00
Jul 14 09:05:28 webserver sendmail[17140]: i6ED4vKP017140: lost input
channel from 218-165-213-230.dynamic.hinet.net [218.165.213.230] to MTA
after rcpt
Jul 14 09:05:45 webserver sendmail[17140]: i6ED4vKP017140:
from=<roughshod0@...>, size=0, class=0, nrcpts=1, proto=SMTP,
daemon=MTA, relay=218-165-213-230.dynamic.hinet.net [218.165.213.230]


The order above is as I found the records in the log file.  It looks
like for some reason milter-greylist was delayed in writing an entry to
the maillog file which resulted in sendmail writing the timeout info and
error state messages then when milter-greylist was freed up it wrote the
record that was pending.  

What is interesting is that the milter seems to grey list the message
but I have had a number of messages drop on through without the
milter-greylist headers.  Again this indicates to me that sendmail went
ahead and accepted the connection and subsequently milter-greylist
finished its activity after the fact.

At the time this seemed to occur the load average was at about 3 or so
and it appeared we were receiving a large number of messages during that
time.

The messages that seemed to get through the greylist without delay were
subsequently caught by spamassassin.

Is this something that has been seen before?  Is there additional debug
data that I can access?

Could the fact that I have a 2 minute delay cause this behavior?  Does
this change the update period for the database file which is causing
milter-greylist to exceed a timeout for sendmail?  Been running this way
for several days and we seem to get all the benefits of greylisting.   

Any help would be appreciated.

Other than this anomaly this milter has been working wonders blocking
spam.
