Unknown value HZ

Question

I get a message that is output from a Linux application (Qt C ++) running on the ARM platform:

Unknown value of HZ! (108) Suppose that 100.

This output periodically appears in different applications with different values in brackets.

It started when I switched from glibc to eglibc-based toolchain for building applications, kernel and file system.

It seems that it does not cause any negative consequences, at least it is not of a direct nature.

Can anyone explain what this means?

This post claims that it means you have been hacked. Here is one with more detailed instructions.

For my Linux CentOS 5, this means the server has been hacked. See how it happened.
