The last reply is pretty complete and explains the issue in detail. Ijust upgraded to 8.1.6.1.0 on Linux and I am still seeing the error. Basically, this issue is specific to Linux and the reason being Oracle does not support the kernel load statistics. It is more of a nuisance seeing the error pop up, the error is bogus. You can disregard it.

Hopefully, this helps you.
