Hi Kim,
        The service listens on a port, each incomming connection causes a
process to be created. This process calles execv on a program, which is
the program that calls CoInitialise().

I have tried all the different flags for createprocess this doesn't make
much difference.

I have tried perfmon, and can't see anything obvious. threads, process,
mutexs ect. go up but nothing that seems to be a limiting factor.

If I kill off some of the initial 30 procs the service will then create
some more processes back up to the limit.

Thanks
