anybody can tell my why when I run dvbtune it says

tuning DVB-S to L-Band:1073858712, Pol:H Srate=27500000, 22kHz=off

Getting frontend event
FE_GET_EVENT: Value too large for defined data type

The frontend event ringbuffer is overflown. Applications should ignore this and check only the last event if there is no explicit reason to check the event history.

and then if I run it again it works
./dvbtune -f 11262300 -p h -s 27500 -n 3003 -i

this is happening every time

Whenever you call dvbtune it will remove one (or more) events from the ringbuffer and so you don't see the overflow anymore.
