Hi Nick,

Is this a CentOS 5 installation that has been upgraded to CentOS 6, but the kernel upgrade was skipped? The kernel compile date dates back to June 2012, thats more than a year; I'm sure you are missing some important security fixes. I suggest you update your OS. > # echo "/tmp/core-%e-%s-%u-%g-%p-%t"> /proc/sys/kernel/core_pattern > bash: echo: write error: Operation not permitted > (running as root) Very strange. Any dmesg logs when doing this? Read about core dumping in "man 5 core". If your system is somehow specific, I would hope its documented there. Regards, Lukas
