The Microsoft Windows Performance API is driven by a set of Microsoft Windows and third-party extension DLLs, which implement the various performance objects and associated counters. These extension DLLs may occasionally return counter values that cause mathematical errors in performance statistics calculations. These messages are reported by the Microsoft Windows Performance API.
These messages are reported by HMA for information purposes and do not have any adverse effect on functionality. They are not caused by HMA. They are caused by bugs or design flaws in the associated extension DLL.
