Am unable to reproduce this phenomen, but it happens sometimes and i just need to reboot kannel service to get the queued MTs go out and sent properly.
here's the kannel status when it's blocking/queuing MTs :

---------------------------------------------------------------------------------------------------- END
And here's the status just after the kannel's reboot, you can see how much MTs were sent
