Recently I started to have problem with Autodisconnect not shutting down my GPRS interface. I can see in the log that it starts monitoring the interface, then after the initial wait interval it gives message "interface closed (externally)" and stops monitoring it. But actually interface is still up. So in result Autodisconnect never checks my GPRS interface. I have tried to toggle settings on/off but that was to no effect.
Any ideas?

EDIT: Rebooting device solved the problem for me.
