Problème Socket Android sujet

Bonjour,



Je développe actuellement une application android avec des sockets et quand je la lance elle s'arrête.Cette application permet d'envoyer des commandes d'une Nexus 7 sous Android KitKat vers un boitier domotique (IPX 800) via le protocole M2M. L'application fonctionne très bien sous Android 2.2 mais pas sur 4.4.2.



Voici le logCat qd je lance l'application :
