by 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
27280 ? SW 0:00 [in.ftpd]
29153 ? SW 0:00 [in.ftpd]
29530 ? SW 0:00 [in.ftpd]

31067 ? SW 0:00 [in.ftpd]
31384 ? SW 0:00 [in.ftpd]
31899 ? SW 0:00 [in.ftpd]

2302 ? SW 0:00 [in.ftpd]
2519 ? 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
