I'm using sendmail and spamass-milter from pkgsrc on netbsd-5. When I use
the -B flag to spamass-milter to forward on spam mail to another address,
when a mail gets forwarded the child sendmail process (often) remains as a
zombie.
So:
1# ps ax | grep 'ZW.*sendmail'
2062 ? ZW 0:00.00 (sendmail)
14832 ? ZW 0:00.00 (sendmail)
16310 ? ZW 0:00.00 (sendmail)
18324 ? ZW 0:00.00 (sendmail)
18553 ? ZW 0:00.00 (sendmail)
19206 ? ZW 0:00.00 (sendmail)
19962 ? ZW 0:00.00 (sendmail)
26535 ? ZW 0:00.00 (sendmail)
28491 ? ZW 0:00.00 (sendmail)
2# grep sendmail.28491 /var/log/maillog
Jan 20 11:00:20 netmanager sendmail[28491]: s0KB0K3A028491: from=root, size=10340,

Restarting spamass-milter gets rid of the zombies. An example spamassassin
run:
Jan 20 13:00:24 netmanager sm-mta[15604]: s0KD0LLF015604: milter=spamassassin,

I can't see any obvious reason why this is happening.
