Have you checked if there are messages locked on modem??
try AT+CMGL and or AT+CMGR=x where x is the sms memory location on the
modem.
I have a similar problem because of messages locked on modem. What I do is
to stop kannel, retrieve all messages on memories and deleted from modem.
Then restart.
I´m not good on C so I don´t know how to patch kannel in order to retry to
retrieve messages once the message memory index it receives from an
incomming message is above half the max modem memory location.
Hope helps
