Here is what my user reports:
- Under extremely heavy CPU Loads, my software app, and the daemon
looses its connection. The user is rendering a lot of imagery on the
same machine. I am assuming that the CPUs are being maxed out with a
lot of threads tying up the machine.
- Just about every user out there with moderate CPU usage appears to
be fine.

What happens that leads you to that conclusion?
Over the past few days I have been documenting (on this list)
problems I've been
seeing with Distributed Objects, and there's more to come, but
whenever my
processes lose communication, there's an associated exception, error
signal,
or warning written to the console:

or at the very least, an unexpected return value:
