Linkit One stop accepting incoming SMS after a moment

I don’t understand why even with a basic program, incoming SMS aren’t accept during a long time.
My program is waiting for a SMS. If Something arrived, it is immediatly re-emit.
I receive on my cell-phone the answer.
All is OK during an undetermined time, and then stop working…
Is anybody meet the same problem ?
it look like " SMS connection timeout and software reboot "

With the latest SDK and the firmare 1.1.05, all problem are solved!
