[Discuss-gnuradio] Not recording it all

I ran my "record" setup for over 10 seconds, but when I run the data file back through my "playback" I only get about two seconds (if that) of result. What happened to all the data, and how can I change things next time to get all the data?

My record setup is as follows:

Rate: 50M
USRP Source
Low Pass Filter
     Decimation: 50
     Cutoff Freq: 15M
     Transition Width: 5M
File Sink
