Replace your memory modules. I've seen some people have those same errors on the lists before, so I did; twice. First, with a replacement set of the same manufacturer 256meg ECC dimms (Micron, I think), and then with the almost-painfully expensive Kentron FEMMA ECC dimms. After switching to the Kentron memory, the crashes were (seemed?) less frequent, but every third or fourth day, ruptime(1) would show that this particular server had rebooted itself during the early morning hours. I could never tell whether it was the result of a panic or a flat-out reboot. I even replaced the motherboard, which didn't help, and fearing software-corruption by all those hard reboots, I reinitialized the RAID volume and reinstalled FreeBSD. Six hours later, while transferring a gigabyte's worth of database files via scp(1), I got another reboot. The following morning, I came in to find the panic I described in my previous post. I was hoping that, to some far more knowledgeable than I, that panic and trace would point the finger at a specific piece of hardware. FWIW, I'm thinking that the RAID controller is flaking, and I've just got to find some time to read the AMI docs to find out if I can swap controllers without causing myself too much pain. Thanks for your suggestion. -- Regards, Evan Tsoukalas Systems Administrator Source Electronics Corporation evan@sourcee.com To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
