Bug #1634
Updated by tuxillo about 9 years ago
Our dragonfly box has got a panic last night. it runs master from last week. I wrote down some text from the panic: mp_lock = 00000002; cpuid = 2 Trace beginning at frame 0xe42d3b88 panic(...) panic(...) exponential_backoff(ff010000, 1 ,3c, e4ad1320, c727dbb) spin_lock_wr_contested(e4ad1320, 0000000) crfree(e4ad12b0,2, e42f3cc4, c00ef73, e42f3c00) nlookup_done(e42f3c00, e4960720, c0304fe3, 0, c0384b5c) sys_lstat(e32f3cf0,6,0,0dd9fce18) syscall2(e42f3d440) Whoever can understand this, can you tell me what happened and how can this be fixed? Also, is there any way to automate this: when panic occurs, automatically start a memory dump process and then automatically reboot? I've been going to the data center way too many times recently to investigate why the box has crashed and it would be very helpful. Petr
