Adb kill-server not responding?

Issue

In ADB, I am facing an error when I am trying to print the version with

padmakumar@padmakumar-desktop:~$ adb version
Android Debug Bridge version 1.0.29

but its showing below error

padmakumar@padmakumar-desktop:~$ adb devices
error: protocol fault (no status)

NOTE: adb kill-server is not working i.e it's not responding.

and in my Eclipse console I am getting this error:

Android Launch!
[2012-01-09 20:31:28 - Shopping List] The connection to adb is down, and a severe error has occured.
[2012-01-09 20:31:28 - Shopping List] You must restart adb and Eclipse.
[2012-01-09 20:31:28 - Shopping List] Please ensure that adb is correctly located at '/home/padmakumar/android-sdk/platform-tools/adb' and can be executed.

Solution

I also came across the same error when I was trying to install one app in emulator. You need not restart PC to overcome this. Just kill the server. if 'adb kill-server' is also not working, kill the process (adb.exe) through task manager. There you go!!
