Has anyone had any experience with the following error in Red Hat Linux? 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. The top command right now shows this output: top - 12:44:49 up 2:16, 1 user, load average: 0.42, 0.21, 0.17 Tasks: 73 total, 1 running, 72 sleeping, 0 stopped, 0 zombie Cpu(s): 23.2% us, 0.3% sy, 0.0% ni, 64.6% id, 11.8% wa, 0.0% hi, 0.0% si Mem: 4144696k total, 1137308k used, 3007388k free, 448k buffers% Swap: 4088532k total, 0k used, 4088532k free, 41672k cached PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND 4256 root 16 0 470m 204m 9204 S 94 5.1 36:01.64 tim 3271 apache 16 0 13164 7068 3052 S 0 0.2 0:01.41 httpd And the system just locked up on me again...3rd time today. Any thoughts or ideas of where to look would be appreciated. Thanks!
