This article was previously published under Q315700 SYMPTOMS
When you are using Performance Data Helper (PDH) in a multithreaded program, all PDH queries in the process may return HRESULT 0x00000102. When this occurs, all queries stop, and the program appears to stop responding (hang) for 15 seconds. After this initial symptom, all API calls to query PDH fail after 15-second timeouts.
CAUSE
PDH is a thread-safe way of programmatically gathering performance data. It is thread safe because of a mutex that controls access to internal
objects. PDH loses control over this mutex, and then becomes unusable in the process.
