General :: ADB Rejected Connection To Client

I have a nasty problem with the adb and my Galaxy Nexus (CM10 nightly-20120926). The ADB seems not to work properly. Every time I start my app within Eclipse it gets installed on my Galaxy Nexus and the LogCat window show some output. So far so good. But suddenly ADB stops writing messages and the "Console" windows shows a lot of messages like:

Code:
[2012-09-26 21:01:15 - DeviceMonitor] Adb rejected connection to client '2930': closed
[2012-09-26 21:01:15 - DeviceMonitor] Adb rejected connection to client '2459': closed
[2012-09-26 21:01:15 - DeviceMonitor] Adb rejected connection to client '2459': closed
[2012-09-26 21:01:17 - DeviceMonitor] Adb rejected connection to client '2610': closed
[2012-09-26 21:01:17 - DeviceMonitor] Adb rejected connection to client '3079': closed

[Code .......

From now on the ADB does not output messages any longer. I have to reconnect my Galaxy Nexus to my USB-Port to restart the debugging.

And some messages I generate by using "System.out.println();" are never displayed also!

My onCreate() method looks like

Code:
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
System.out.println("ON_CREATE!");
[...]

But "ON_CREATE" will never be displayed!!
