My unRAID server (Intel Xeon X3470 / SuperMicro X8SIL-F-O / 16GB 1333MHz DDR3 ECC / SuperMicro AOC-SASLP-MV8) running 6b15 Pro have crashed twice now. First, while I was transferring files over the network. Second, while trying to rebuild the array from the crash. Both times, I've received the following error:
Kernal panic - not syncing: Timeout synchronizing machine check over CPUs
Shutting down cpus with NMI
Kernel Offset: 0x0 from 0xffffffff81000000 (relocate range: 0xffffffff800000000-0xffffffff9fffffff)
I've tested this server extensively Memtest (3 days+), drives were precleared 3 times, CPU was tested thoroughly for stability.
