You probably are creating all your threads as scope system
threads.  Each scope system threads consumes a KSEG (limited
by kern.threads.max_grpups_per_proc).  I don't think you
really need each thread to be scope system; try making
the port use scope process[1].  If you insist that it does
need scope system threads, then raise max_groups_per_proc.

[1] To anticipate the question, "will one thread blocking
    block the entire process", no, other threads will be
    run.
