1. in.ftpd zombie problem with wu-ftpd on RH6

We're using wu-ftpd-2.5.0-2 on RedHat 6.0.  The server is working
fine, but we have noticed the following problem:

After several days of operation, there will be many 'leftover'
in.ftpds.  We allow 100 users at a time and this is resulting in users
being denied access to the site even though there are only 3-4 active
connections.

If you do a ftpshut followed by a killall in.ftpd, then all is fine
for several more days.

Once the problem develops, a ps shows:

# ps ax | grep in.ftpd

29153 ?        SW     0:00 [in.ftpd]

<many more follow>

wu-ftpd is being launched from inetd.conf as follows:
ftp     stream  tcp     nowait.255      root    /usr/sbin/tcpd in.ftpd
-l -a -t240 -T240

Any ideas on solving this would be appreciated.

Thanks,
Brian
