Ivan,
Thanks for sending that along. From a software perspective, what
parameters do you input to your attached code to run it? I'm trying to
understand the data rates you're trying to sustain over the NIC you
have. I've been combing through this past USRP-users thread for some
additional insight:

Based on some of those suggestions, it might be wise to try finding
another NIC to bring into the equation.

Indeed, I just noticed the 82574L/LM referenced in the original complaint.
Those types of NICs have issues that cause packet loss--there have been
a few "workarounds" over the years in various kernels, but none of
them actually 100% fix the underlying issue with those chips--they're
basically broken. You don't notice this with web-browsing and
other TCP-based protocols, because those protocols do error recovery.

What hardware are you using on the host side? Specifically,
I'm interested in CPU, RAM, and NIC.

Hello. When I read data from the board, error D
periodically passes. It leads to bursts in the spectrum
that fits in the figure. Please tell me how you can remove
this error or how it can be handled? I also attach the
code file.
