Problems with 3B2/310 and WIN/3B

Maybe someone out there has had a similar experience, if so *pleez* help:
We are running Wollongong's WIN/3B 1.1 on three 3B2 310's, (SysVR3.0).
Lately I've had some problems with memory management in the packages
driver. The console will display "Sh: no buffer space available"
repeatedly. Well, a "netstat -m" (display memory usage) will show that,
of 512 "mbufs" available for use, usually > 500 are in use. (I have
found that a typical "rlogin" will use ~15 mbufs).
The *real* annoying part is that, when I find this unusual problem,
a "netstat -A" (show active connections) will sometimes reveal that
an "rn" or "rlogin" connection was left hanging (with no controlling
process) and other time will reveal NO active connections.
I have found no way to deallocate this memory short of a
complete POWERDOWN!
I would like to know if anyone else has experienced this, and if so,
how the heck can I deal with it? I would be happy to find or write
a program that sends an ioctl down to the driver to tell it to
deallocate the memory. The documentation for WIN/3B leaves something
to be desired...
Thanks in advance.
