Subject: Idle timeout does not work?

Guten Tag!

Unfortunately, we here at ftp.germany.eu.net have a rather bizarre problem
with the wuarchive ftp server, version 2.4(5): Although there is an idle
timeout period of 900 seconds configured the ftpd tends to not log out idle
users so we have to kick them out "by hand" with kill.

Do you know of any circumstances which may cause the idle timeout mechanism
of the wuarchive ftpd to fail? Are there any bugs in the alarm() system call
which is used for the idle timeout? Our machine is a Sparcstation 5 with
"uname -a" reporting "SunOS simpson 4.1.3_U1 1 sun4m".

It is important that we can fix this problem because our ftp services are
quite often blocked by idle users.

Thank you in advance for you help!
