So you're not seeing any exceptions in the log? Genie defaults to the
30 seconds timeout or whatever you have specified in config.json. The
device may also suggest a session timeout value in the inform message 
but I doubt your device sets the timeout to 5 seconds.

This is likely a bug. I have a few fixes coming up tomorrow so that
will hopefully get resolved. But let me know if it doesn't.

It's possible that the device sends "Connection: close" header. A CWMP
session can span across multiple TCP connections so this could be
normal.
