         Wollongong Integrated Networking WIN/3B: Release 2.1
         AT&T 10base5 Network Interface (NI) Package: Release 1.1

         We are running the above on our AT&T 3B4000/15 and have been experienci
ng
         frequent "crash" on the network. To bring the network up, we have been
         using sysadm netstart. However there are times where we had to start an
d
         shut several times before we establish the network correctly (able to
         telnet). Also, we had taken the default configuration of 8 ttyp ports b
ut
         sometimes when there's only 5 ports used, users are given the message
         "All network ports in use" when they try to telnet or rlogin into the
         system.

         Usually when we are desperate, we just reboot the whole system...works
         perfectly so far!!

         I am just hoping that there are users who had this problem and if there
's
         some better solutions to it.

         Thanks.

Release 2.1 contains a number of bugs -- enough to make it almost
unuseable. About the only solution is to upgrade to WIN/TCP 3.0.

You also need to do some heavy tuning of the kernel parameters.
We run with the following parameters:

	master.d/tcp	NTCP=64
	master.d/ucp	NUDP=128
	
You also need to crank up some of the streams stuff (TIMOD & TIRDWR)
but I don't have the specific values handy.

Pity.
