Subject: TIS gateways not observing timeout

Hi,

I've been using v1.2 (and the newer 1.3 beta) of the TIS ftp-gw on my SGI
gateway host for several weeks now and have noticed that I can have many
ftp-gw processes running that are several days old. Right now I have
20 of them and while they are relatively "lightweight", they do still
consume resources.

I have a "timeout  3600" in my netperms file, but I'm still getting lots
of these things hanging around, obviously _long_ after any real data has
passed through them. Should they be dying off ??

Marcus Ranum (the toolkit's author) says so:

>        They *should* be, yes. Basically the timeout value is passed to
>select (for all descriptors) so complete inactivity on all of them, for
>the time stated in the timeout, should cause the program to exit.

So, has anyone else seen this problem at all?? Is it a possible problem
with the use of select() under Irix 5.x ??

        ian

PS this is under Irix 5.1.1.3 on an Indy.
