Hey look at that. My previous message has been robbed of line breaks and the
first part of
this thread has gone missing. Looks like the html I embedded really confused
things. Here's
a more readable version of my last message. I'll let Derek know that this
thread needs to be fixed...

param_init() and param_calc() figure the global and per user limit on the max
number
of processes. It depends on a few things like the max number of users, amount
of memory, etc.
On an x86 test machine i'm seeing:
v_proc = 0x207a
v_maxup = 0x2075

8314

8309
So around 8300 for both. The "c_" tests deal with some number of
processes/threads that are handing locks around in a ring. The "_10"
tests should be creating 10 processes, the "_200" test should be
creating 200, etc...so it's interesting that you're hitting what seems
like should be a limit of 512 when the test is creating at most 200
processes....
I could see this happening if libMicro wasen't waiting for the
processes from one test to terminate before starting the new test, or
if there was some delay in the OS between the time a process exited
and the time that it's resources are returned to the system...
