FYI, I experienced similar kernel panic issues with our SCOUnixWare z/VM system this past spring...
IT is running on an IBM Netfinity here at the Air Base. After four days of consecutive crashes...I finally called IBM Hardware support in Atlanta. They replaced the mother board in our 8668 eServer and the Unix kernel panic problem went away! Call the hardware vendor of your server and have captured digital photos of the panic available for them. Jest of our hardware problem was the internal system board battery on the mother board was getting weak and could not sustain the hardware environment, and the IBM BIOS did not warn us of the problem of the weak battery! IBM has a fix for this however as I was notified by their list server e-mail yesterday that new BIOS is available to warn of a weak internal battery! Place a call to your hardware service vendor...

Kernel panic - not syncing: Out of memory and no killable processes error and system is frozen and has to be hard rebooted. cat /etc/redhat-release output is: Red Hat Enterprise Linux ES release 4 (Nahant Update 4). uname -a output is: Linux timmon1.corp.bcbsks.com 2.6.9-42.ELsmp #1 SMP Wed Jul 12 23:27:17 EDT 2006 i686 i686 i386 GNU/Linux I have a screen print of the console when it's frozen, but didn't know about attaching a graphic to a question. I also have a meminfo.out file and sysreport output that I can send if anyone thinks that would be helpful. We've changed the setting for lower_zone_protection as recommended from Red Hat and it's not having any impact on this problem occuring. Setting change from Red Hat: echo 100 > /proc/sys/vm/lower_zone_protection We've had this problem occur off and on with both of our Red Hat systems, but this one in particular has been having a major problem the last week and has been locking up about 3 times a day. We use the Linux systems with our CA Wily product for monitoring on the network.

Any thoughts or ideas of where to look would be appreciated. Thanks!
