Not. I ran 'procstat -k 11 | grep 100006' about 20 times, and all but one looked like this: 11 100006 intr swi4: clock mi_switch ithread_loop fork_exit fork_trampoline The one that didn't looked like this: 11 100006 intr swi4: clock mi_switch turnstile_wait _mtx_lock_sleep _mtx_lock_flags lock_mtx softclock intr_event_execute_handlers ithread_loop fork_exit fork_trampoline It just ran away again with the only change being cx_lowest=C1. I'll try changing the event timer next. Doug -- Improve the effectiveness of your Internet presence with a domain name makeover! http://SupersetSolutions.com/ Computers are useless.
