Hi,
	We've recently upgraded our Interactive Unix, TCP/IP and NFS to 
the latest version (2.2) and are running MOTIF.  I'm doing 
graphics work in X and have been running into an error message frequently.
The message is PROBLEM WITH PTR PACKET - OVERFLOW. I only get this error
when I'm in X and when it occurs it'll usually slow down the performance in
X and may sometimes not respond to any mouse events at all.  I had called
Interactive about it and they suggested increasing the NSTREAM and NQUEUE
kernel parameters. I increased those to the maximum values permissible and
the error still occurs.  Any ideas ?
	In an unrelated event, I had increased my system's RAM from 8M to 10M
and there's still no significant improvement in the speed of MOTIF and
related stuff. I have a 386/20 and the abovementioned operating system.
I re-configured the kernel parameters, namely the NBUF, NHBUF but that didn't
help the speed at all.  Any recommendations as to increasing the speed of my
X windows (MOTIF) ?  Thank you for any help you may offer.
