You specified that this happens under a heavy load. With the newer OS ans Oracle the hardware may think that the server is locked up. Or you may actually be experiencing a lock-up and the BIOS setting causes a reboot There could even be a simpler reason for this problem. We had a server do this very thing under REHL-3 and it turned out to be hardware related. The servive technicians came in and reset the the memory, CPU, replaced the CPU fan, and reset the bios. Our problem may have been to over heating after the system was up and running for a few hours. No upgrade to the bios was needed in our situation. This system is only about 2 years old and is rack mounted. Be sure you have enough air flow to and around the system. -------------- next part -------------- An HTML attachment was scrubbed...
