Hi Sean,

 I am not using UHD blocks, I am using osmocom source/sinks. I did not see any warnings about changing buffer sizes.

 Thank you,

Unless I'm mistaken, only the usrp sink/source blocks report overflow (source) or underflow (sink). You can see this mentioned in uhd/docs/general.dox (uhd github repo).

Did you listen to the warnings you get on startup about changing buffer sizes with a series of commands requiring sudo? That helped me resolve some overflow, otherwise it sounds like you'll need to drop your sample rate unless you need it as high as it currently is.

 Is there a way to diagnose which block first reports an overflow in a flowgraph? 

 In my particular instance I am running a flowgraph which is overflowing without pegging either RAM or CPU. 

 Thank you,
