Have you taken dumps and made them available to HP RC?  I've got at
C5501 system (5.5 + PowerPatch Tape #1) with a 8 user license.  And as a
result of a question from a customer tested that I can run 8 NS-VT
sessions w/o a problem; #9 gives an error.  This, in my mind, says that
basic UBP features are working.  Likely there is something special on
your system that I'm not emulating (YMMV!) AND it doesn't appear you
have a straight UBP problem.

If the system allows new logons then the HPRC may be able to dial-in and
look at the system live with PM Debug.  Also, "performance" tools like
Glance might tell you a little more about the process state, especially
if you look at a stack trace....
