Max # of procceses on RS6000

[Marc Cooper]

Ok, unsubstantiated rumor time...

I have heard that running AIX 3.1 (I think that's the right number) on an 
RS6000 530, there is an undocumented "feature."  Namely, that there is a
maximum number of processes that can be running simultaneously.  I am 
NOT alking about maxuproc, which, by default, is 40.  That only controls how
many processes each user might run.  I'm talking ALL processes, total!

The way I hear it, if the unspecified max number is exceeded, the machine 
will start killing off the most resource hogging jobs, which in my case
happen to belong to a research chemist who would be VERY upset if 
his calculations started dying.  

Is there a maximum nimber of total processes the 6000 can handle?  If so,
what is that number?  And what happnes when you try to exceed it?
