Well, I’ve seen similar issues before. CentOS 6 is way too old; it’s EOL for 2 years already. I suggest you either upgrade your OS and if that’s not possible use an older version of the agent that is supported on CentOS 6.

Where do I find the older agents? Yea I know its EOL and working with my current client to quickly get this updated but its high visible production box.

On the CheckMK download page. You can download the server RPM for 1.6.0p30 there. It includes the client.

You can then extract the contents of the RPM archive and get the CentOS 6 client rpm from there. To extract an RPM package without installing it you can use rpm2cpio and cpio to extract the contents.
