New Programmer Adb Connection Error In Eclipse

I keep running into an ADB error when opening Eclipse. I receive it continuously every 10-20 seconds: [2011-08-24 21:25:40 - DeviceMonitor]Adb connection Error:An existing connect

Solution 1:

I'm not sure what is going on but try the following and see if it helps:

• close eclipse
• run the command "adb kill-server"
• kill all running instances of the adb process
• restart eclipse

If this doesn't work try running the command "adb devices". Any error messages here?

Solution 2:

As THelper replied you might have connected to device or already a dead emulator might be opened
