Failing "mfeatp" application (0xc0000409) - cause?

Looks like my Threat Prevention module keeps crashing and is being restarted on one of my control systems workstations. Every few hours / days the following event is logged (it always fails with the same 0xc0000409 exception code):


Faulting application name: mfeatp.exe, version:, time stamp: 0x5f3fd043
Faulting module name: DeepRem.dll, version:, time stamp: 0x5e7e0276
Exception code: 0xc0000409
Fault offset: 0x0000000000099cf4
Faulting process id: 0x1828
Faulting application start time: 0x01d73dc7b4c9dd7f
Faulting application path: C:\Program Files\McAfee\Endpoint Security\Adaptive Threat Protection\mfeatp.exe
Faulting module path: C:\Program Files\McAfee\Endpoint Security\Adaptive Threat Protection\DeepRem.dll
Report Id: aa2fc24c-5bde-4ef6-8e52-ff1bf0f8bec7
Faulting package full name:
Faulting package-relative application ID:


Does anyone have an idea what could the root cause be or if there is a know workaround?

I would rather avoid reinstalling it at the moment.
