In one minute she fired several exceptions like that /\
It always happens about 5 days after starting the app and it stays 24 hours online.
I’ve researched about, but didn’t really find the problem, maybe it could be some open connection, but I close all connections.
Does anyone know why?
Obs: I use JBOSS 7.1.1
