Hi List,

I am getting the below error on my rhel server. Mysql is running on this
box.

Due to below error server hangs and stop responding. After system reboot
it's working.

Is the error related to mysql. Any body else facing similar issues.

Thanks,

the oom-killer is a kernel function that shoots down [large|random]
processes when you start running out of memory. Google is your friend, as
are RAM vendors :-)
