We have been all through that phase of NBU 5.0MP2 and you will continue to
have problems until all clients are at the 5.0MP2 level.  Also VSP will be a
problem until that point also.

It will do no good to upgrade to 5.1 as the fix for VSP and the client hang
problems is not in 5.1 yet.

So far 5.0MP2 as long as it is installed in all clients is very stable.  Any
client not at that level will give trouble and have to have VSP turned off
for that machine.
