Hi, I've kicked off 3 2G vm's which do a continous while(1) { make -j 4 buidlworld } And one of those VM's just crashed with the message below. Observation: The VM is clearly not able to recover from this. And probably needs to be destroyed and restarted... Don't know it it got as far as vmrun.sh restarting it. Question: 1) I expect this to be due to 3 VM's running in parallel with quite some load. But is this something that needs to be reported to stable@? Or does this belong here on this list. 2) Killing the VM and restarting probably also kills the memory but not the swap? And thus would allow to extract a core? I'll see when I reboot. --WjW ==== spin lock 0xffffffff814fa030 (smp rendezvous) held by 0xfffff80079e8d490 (tid 100097) too long timeout stopping cpus panic: spin lock held too long cpuid = 3 KDB: stack backtrace: #0 0xffffffff808e7dd0 at kdb_backtrace+0x60 #1 0xffffffff808af8b5 at panic+0x155 #2 0xffffffff8089cb71 at _mtx_lock_spin_cookie+0x241 #3 0xffffffff80c7ec7a at smp_tlb_shootdown+0x8a #4 0xffffffff80c8066c at pmap_invalidate_range+0x2fc #5 0xffffffff80932f6d at allocbuf+0x55d #6 0xffffffff809317cf at brelse+0x14f #7 0xffffffff80934b18 at bufdone+0x78 #8 0xffffffff809346c2 at biodone+0xe2 #9 0xffffffff8081c561 at g_io_schedule_up+0x1b1 #10 0xffffffff8081ca5d at g_up_procbody+0x6d #11 0xffffffff8088198a at fork_exit+0x9a #12 0xffffffff80c758ce at fork_trampoline+0xe Uptime: 1h21m3s Dumping 183 out of 2025 MB:..9%..18%..27%..35%..44%..53%..62%..79%..88%..97% Dump complete Automatic reboot in 15 seconds - press a key on the console to abort Rebooting... cpu_reset: Stopping other CPUs timeout stopping cpus cpu_reset: Restarting BSP cpu_reset: Failed to restart BSP ====
