Hello, We run the Oracle Application Server 10G on RHEL4u6. I had problems in the past with newer kernels released by RedHat causing system crashes, so I rebooted the machines to an older kernel version 2.6.9-11.ELsmp which keeps the machine stable, does not crash. The machine booted with a newer kernel will crash some 30-45 minutes after reboot? We encountered this problem numerous times, and this is a PROD environment. Also on my boot parameters is added noexec=off per a suggestion in the past from Oracle. Anyone have any ideas about this issue? Stephen L.
