Hi! With a 9.99.47/amd64 kernel from February 16, I just had panic (handcopied):
panic: kernel diagnostic assertion "curcpu()->ci_biglock_count == 0" failed: file .../kern_exit.c line 214: kernel_lock leaked cpu12: Begin traceback vpanic kern_assert exit1 sys_exit syscall -- syscall (number 1) -- 70497d18609a cpu12: End trackback... Mutex error: mutex_vector_enter,542: locking against myself lock address: 0xffffa5ce94444b40 current cpu: 12 current lwp: 0xffffa5cbee57da80 owner field: 0xffffa5cbee57da80 wait/spin: 0/0 Skipping crash dump on recursive panic It might have been a low-memory situation -- it was running a bulk build and had some network activity.
