apns sandbox connection crash

[simonxuhao]

Hi,

When my app starts, it creates both apns and apns sandbox connections, sometimes the sandbox connection crashes (exception exit: {in_closed,timeout}, see below), why is this happening? Will apns4erl recreate the connection? Should I add some code to handle connection lost?
