It's 3 am and I'm not getting anywhere...I seem to be having a small problem with sendmail. I have compiled sendmail+ida 5.65 for hp-ux 7.0 and everything is working real nicely. The IDA extensions are real helpful. My problem is that after a smtp connection to my sendmail, the process that was fork'd from the daemon to handle this connection does not exit..it becomes a <defunct>. Read the man pages on how this should work and found out that the parent process should wait(). Well, the parent process does do that and I verified with some "syslog()"'s. So, why does the child still hang around as <defunct>? Has this happened to anyone else? Reply by post's or email depending on how crazy this message is. Thanks.

Processes with pending I/O can become defunct when terminated abnormally. I've seen this happen on ptys when the master side process dies and can't be read from the slave. If the slave was then killed it became defunct (hung in exit() somewhere). I guess there are lots of other ways this can happen, probably mostly on slow devices. Rob Robason
