Just found a hyper-v server running at 100% on all 8 cores. Task manager showed that monitoringhost.exe was the culprit.
Monitoringhost.exe is an agent of System Center Operations Manager 2007 and is used to report back the status of a server. Stopping and Restarting the OpsMgrHealth Service cleared the problem. A little more digging found that this is a known problem and there is a patch available from Microsoft to fix this:
This is a really annoying problem and appears to be fairly common to Sony SZ model laptops.
The mouse touchpad can randomly reverse it’s direction, so when you slide your finger left, the pointer goes right. The same is true of the vertical – slide up and the pointer goes down! Very frustrating!
Researching this it appears there are several possible causes, some due to faulty drivers and some due to faulty hardware. Here are some pointers (pardon the pun!) to help fix the problem:
1) Restart the process apoint.exe
Open up Windows Task Manager, and terminate apoint.exe
Go to c:\Program Files\apoint and then click on apoint.exe (the icon should look like the touchpad in the taskbar)
2) Disable Wheel Detection
Go into Device Manager -> Mice and other Pointing Devices -> Synaptics PS/2 Port Pointing Device
Select Properties -> Advanced Settings
DISABLE Wheel Detection (set to Detection Disabled)
Un-check the Fast Initialization box
If the above doesn’t help, you’ve probably got a hardware problem. If you’re feeling brave, there’s a good walkthrough of how to fix the problem here.
