Error message looks like you have a hardware problem with CPU or RAM. Have you tried running
memtest
or if available, a built-in hardware diagnostic tool which you can choose during the server boot?This is definitely look like a hardware error.You can try tool like mcelog which just act as a translator for any machine check exception(mce).You haven't menrioned which version of OS you are using but in RedHat/Centos you can install it via yum
