zombie processes

[Nerijus Baliunas]

Hello,

On a Debian woody box with exim3, I get zombie process after
starting MailScanner:

# ps axw|grep -i mailsc
15355 ?        S      0:00 MailScanner: starting children
15356 ?        S      0:00 MailScanner: waiting for messages
15360 ?        Z      0:00 [MailScanner <defunct>]
15366 ?        S      0:00 MailScanner: waiting for messages

After some time:

# ps axw|grep -i mailsc
15355 ?        S      0:00 MailScanner: master waiting for children, sleeping
15356 ?        S      0:00 MailScanner: waiting for messages
15360 ?        Z      0:00 [MailScanner <defunct>]
15366 ?        S      0:00 MailScanner: waiting for messages

After message is received:

# ps axw|grep -i mailsc
15355 ?        S      0:00 MailScanner: master waiting for children, sleeping
15356 ?        S      0:00 MailScanner: waiting for messages
15360 ?        Z      0:00 [MailScanner <defunct>]
15366 ?        S      0:00 MailScanner: waiting for messages
15396 ?        Z      0:00 [MailScanner <defunct>]

Sometimes some zombies disappear and new ones appear, but usually
there are 2 of them. They don't seem to be doing any harm and they
disappear after stopping mailscanner, but still something is wrong.
Any ideas? Nothing wrong in logs.
