[Discuss-gnuradio] Getting overflows at 50 Msps (not sure why)

[Orin Lincoln]

Hello,

I am trying to get samples from a B200 at 50 Msps into GNU Radio. The 
UHD benchmark_rate tool receives at 50 Msps without any overflows 
detected. My GNU Radio flowgraph is simply a USRP source connected to a 
null sink, and I'm still getting overflows. I've tried expanding the 
min_output_buffer for the USRP source, but that doesn't seem to help. I 
really don't know what is causing the problem. Any suggestions about 
what I should try?

Thank you,
Orin Lincoln
