"DeviceMonitor]Sending jdwp tracking request failed!" in Eclipse / Android

I'm a noob learning Eclipse and Android. Whenever I close the emulator I get "DeviceMonitor]Sending jdwp tracking request failed!" in the Console tab. Infact that seems to be the ONLY thing I get in the console tab - I don't get all the emulator loading messages and other things I used to see.

Everything else seems to work, I can build, run in the emulator, debug in the emulator (via Run>Debug after setting a Debug configuration . . . I can't get "Debug As" to work, see: "Debug As..." in Eclipse for Android - don't know if that's relevant to this problem).

What does this message mean, and how do I correct it? Thanks in advance!

The message you receive is in the normal console of Eclipse and isn't really important, because it just reports you that the connection to the emulator was lost. That ok as you described you closed it.

The normal android log is only visible via the adb tool (via console) or with the view in Eclipse called LogCat. You can add that to your working screen if you go to Window -> View -> Other -> Android -> LogCat

I recommend to look at the other views of the android tools, too. Like Device or Explorer.

What might happen with the LogCat output is that it went blank. Than you need to clear the LogCat (there is a button for that on the top of the view) and if this doesn't help try to click on the emulator in the device list. If nothing of that helped: close eclipse and the emulator and start them again.
