Unknown HZ Value

Question

I'm getting a message that prints out of a Linux application (Qt C++) running on an ARM platform:

Unknown HZ value! (108) Assume 100.

This output shows up periodically in different applications with different values in the parenthesis.

It started happening when I switched from a glibc to eglibc based toolchain to build the applications, kernel and filesystem.

Doesn't seem to be causing any ill-effects, at least not of an immediate nature.

Can anyone explain what this means?
