Very large value, is this a typecast / intsize problem ??

no. it looks like for some reason you are loosing tons of uplink TCH frames
in you setup. Every 20 milliseconds we expect one TCH block equalling
160 sample clocks at the 8kHz audio sample rate used in GSM.
There may be some underflow/overflow issues in the modulo arithmetic of frame numbers.
The important fac is not so much what exact figures you see here, but that
you see such messages regularly at all. There's something very wrong here.
