All of them show the thread executing in unp_gc() like here: ---- unp_gc() at unp_gc+0x81 taskqueue_run_locked() at taskqueue_run_locked+0x85 taskqueue_thread_loop() at taskqueue_thread_loop+0x46 fork_exit() at fork_exit+0x11f fork_trampoline() at fork_trampoline+0xe ---- See all samples under [3].
