Milter-greylist

Since putting milter-greylist 2.0 into production a few days ago on a
low- to moderate-volume Sendmail 8.12.10 system, it's started failing
regularly after about 24 hours of operation.

During the live testing phase, I had it set to greylist about 8
addresses and whitelist everything else. During that time I never
observed it to die. When I put it into production, I removed the 'acl
greylist rcpt' and 'acl whitelist default' lines and replaced them with
'acl greylist default'.

Symptoms of the failure are the following lines in the syslog:

Jul  9 13:34:23 bluebird sm-mta[5352]: j69JYDPV005352: Milter (greylist): timeout before data read
Jul  9 13:34:23 bluebird sm-mta[5352]: j69JYDPV005352: Milter (greylist): to error state
Jul  9 13:34:23 bluebird sm-mta[5352]: j69JYDPV005352: Milter (greylist): init failed to open
Jul  9 13:34:23 bluebird sm-mta[5352]: j69JYDPV005352: Milter (greylist): to error state

During normal operation there are five milter-greylist processes
running. When failure occurs, there's only a single running
milter-greylist process.

For the failure reported above, the greylist.db database was last
written about 13 minutes before the crash and contains 654 records.

I have not yet noticed any pattern in the messages which it processes
just before failure.

I'm going to investigate further with a debugger to see if I can
determine the cause.
