Hi
It does happen with some phones when your phone memory/sim is full. In
those phones, it fails to report smsc that it received the "last" sms that
fits its memory; therefore smsc never receives the delivered PDU, and thus
kannel retries until it expires. This usually happens when storing sms on
SIM.
Try to delete some sms from phone memory and sim.
Regards
Alvaro
