Possibly do you also have problems with window system hanging??

We seen sort of similar problems.  They were solved by increasing
the amount of system paged dynamic memory (PAGEDYN system parameter).
VWS likes lots and lots of PAGEDYN, as referenced by the SHOW MEMORY
output from one our VAXStations (system was idle at time, I logged
in with SET HOST):
