[vz-users] vzlogger stirbt

[Andreas Brus]

Endlich habe ich auch den aktuellen vzlogger mit s0 und 1wire im Einsatz.
Erstmal lief er einige Stunden brav und stabil.
Leider stirbt dieser nach einer bisher unbestimmten Zeit mit folgenden 
Meldungen anscheinend mehrere bevor der Prozess endgültig stirbt.
