I've been having problems with NCSA Telnet freezing my machine after it
runs for a while - I finally decided that my heap was probably a bit full,
so I ran the program BootEdit that came on our Kinetics software disk,
(with the ethernet stuff) and allocated another 16K to the heap.  I haven't
had any lockups since.  So, the moral of the story is, make the system heap
bigger.  Mine is currently 176K.
