Environment
McAfee Endpoint Security (ENS) Adaptive Threat Protection (ATP) 10.5.4, 10.5.3

Memory consumption by mfeatp.exe continues to grow beyond 300 MB. mfeatp.exe is provided as part of ENS ATP.
Cause
This symptom can occur where the Threat Intelligence Exchange Server and Advanced Threat Defense components of the threat reputation ecosystem also exist. The leak we have identified and resolved occurs from WinHTTP/webio handles being created and not being released when Advanced Threat Defense interacts with these components.
