I have seen these crashes on my box since 6.3 pre-release, randomly, but under load. My box is based on a SuperMicro motherboard running Intel Xeon processors. The only commonality is that we're both using Sata drives. John, a question, how is swap set up on your system? I was swapping to a file (a memory disk device /dev/md0). I was doing this because for some reason lost in ancient history, this machine was not set up with a real swap partition. Hence, no crash dump. Last night I repartitioned a second disk, set up a real swap partition and now I'm currently waiting for this to happen again so I can get a crash dump. Michael Grant
