Bordermanager 3.7sp3

Please excuse me, my skill level is lower than most. On my novell server
that handles my proxy some outgoing connections do not end when the user
has logged off of a machine. Instead they stay active and make the outgoing
connection very slow untill they timeout or I restart the proxy service. I
am able to locate these connections by runing the "_dumpnattcp" command.
I'm sorry if I haven't explained my situation well enough.

I am wondering if there is a fix for the problem im having, if there is a
command I can use to clear the dead connections, or if I can change the
amount of time it takes for connections threw the proxy to timeout. Any
help would be great.
