wfreerdp.exe and w3pw.exe are causing high CPU utilization

[BarryLiu04]

wfreerdp.exe and w3pw.exe randomly cause high server CPU usage (over 95%). Normally, the cpu utilization is around 5%-15%. Does anyone know the underlying cause?

Maybe some lack of available RAM? do you have something relevant in the Windows event logs (System or Application)?

From what we see, the Memory Usage(%) never exceeded 80%.

Found this from Myrtille.Web.Log. Not sure if it's relevant.
