Hello, my name is Peter Hubberstey and I work for a small ISP in the UK.
I have compiled a new version of QPOP (version 3.1) some time ago and run it
bound to port 2000. I informed a few of our technically literate users and
asked if they could test it.
The testing has gone OK for some months now ( about 3 ) so last night I
decided to change the main version.
I decided to rem the line from the /etc/inetd.conf and restart the inetd
daemon and run popper in stand alone mode instead. We have about two
thousand customers using this server and whilst probably a maximum of around
10 or so ever collect mail at any one time, the disks are IDE so I figured
that popper's server mode would be a better choice.
So I run the daemon.
/usr/local/popper -SscT 120
All Fine.
Checked this morning and I know have loads of "defunct" task
check out the ps -ef

Trouble is I have found that by killing the defunct tasks, it brings down
the main daemon too.
Any known problems? Suggestions ?
