You probably have bad memory. Run memtest on your machine.

Please spell your words out. As AlucardZero said, this is probably bad memory. A quick Google search could have given you the solution. What version/distro of Linux are you using, and what have you tried??

Also please post machine brand and type, hardware specs, RAM bank population (even or not) and if running a previous kernel works.

Apr 15 10:24:04 cnlx100 kernel: MC0: CE page 0x3c66, offset 0x1a0, grain 8, syndrome 0xd6b4, row 0, channel 0, label "": k8_edac


And version is like this

You probably have bad memory. Run memtest on your machine. You need physical access.

Again, SPELL YOUR WORDS OUT, and we have "kindly given" you a solution, but you don't want to hear it. Sorry, the only thing you can do is to replace the bad memory on your machine....that's it. So either replace it all with brand new memory, or wait until it totally fails.

You obviously REPLACE THE BAD MEMORY. Open the box...take out the old one...put in new one.

Again, SPELL OUT YOUR WORDS. And no, it isn't...that's like asking "Gee, my car is broken down...if I put new air in the tires, will it run?"

You'll need to tell the local IT guy that his server's RAM is broken so he will go in and replace it.
