I can't think of a case when this would happen. What evidence do you have that data is being dropped? Can you hook up a siggen and feed a single sinusoid to the USRP rx daughterboard? Tune the USRP so that the sinusoid is not at DC in the complex baseband, and log that data using your program and/or usrp_rx_cfile. Then use octave or some other tool to look for discontinuities in the received signal. This would allow you to confirm or refute the existence of the discontinuity using a much less complicated detector than your GPS receiver.
