If you have the docs for LWP there is a section on tuning
the TCP/IP parameters in the net.cfg. If you don't and you
e-mail me, I'll cut of my net.cfg and mail it back with a 
short explanation from the docs. Right at the bottom of
your current net.cfg there should be a couple of lines for
tuning things like window-size, buffers, etc. that relates
to the tcp/ip. You can run into problems with the tcpip part
being out of sync with the memory/buffers part at the top
of the net.cfg which is why I strongly recommended the docs.
It won't usually stop working, you just may get a bunch of 
warning messages.
