There should be, but currently isn't.  The uO means that the USRP Rx
path is overrunning.  That is, it's not being serviced in time and you
have gaps in your data.

I suggest you try a higher decimation rate.

There are hooks in the code for a general purpose error handler which
can redirect output anywhere.  The USRP code needs to start using it.
