Android - Logcat Launch timeout has expired

When running LogCat in Eclipse, the output to Logcat stops after the following message

 08-19 19:46:13.525: WARN/ActivityManager(58): Launch timeout has expired, giving up wake lock!
 08-开发者_C百科19 19:46:13.702: WARN/ActivityManager(58): Activity idle timeout for HistoryRecord{43fd5c90 com.android.homeopathy/.symptomActivity}

What does this mean and why does the output to Logcat stop at this point?

I've had some mionor problems with Logcat in eclipse as well. I chose the easy way out and use ddms now.
