What is causing ‘adb server is out of date. killing…’ error?

As we know this problem is faced when we try to debug by connection to PC via USB, the phone detects it. The sync application of our phone detects that you have connected to your PC and tries to forward an IP/TCP port to it.

From its directories, the phone sync application runs adb.exe to forward the IP/TCP port. Then when you attempt debugging it with Android SDK, it launches adb.exe. 

Even so, the later adb.exe recognizes the former adb.exe which is running and kills its operation. 

The whole process breaks the port mapping. The phone sync application detects this faulty port mapping. It then starts the adb.exe from SDK. And once this sets in before the debugging is complete, the message ‘adb server is out of date. killing…’ will appear on the screen. The debugging will then be terminated.

This is the main cause why ‘adb server out of date’ pops up during debugging process.
