Dear Marcus,
/Is this happening on BOTH USRPs?/
Yes, it happens with both USRP randomly.
/Have you followed this guide here for performance tuning?/

Yes, I have followed your advice. The only thing I haven't dared to
touch is the grub.
/I have an X310 with two TwinRX, on Ubuntu 22.04, UHD 4.1, and I
can stream literally for *days* without any issue
at all./
Well, That is my goal but I don´t know how.
/How are you connected to your X310s? If you only run one at a
time, do you see this failure?/
They are connected via dual 10GB ethernet ports and each port is
connected to a different network card to ensure there are no
limitations. I get the same behavior with a single USRP.
I have tried to apply the configuration indicated in this example:

But the same thing keeps happening.

What about the ring buffer settings?
https://kb.ettus.com/USRP_Host_Performance_Tuning_Tips_and_Tricks
The ring buffer settings aren't persistent across a reboot, so you
either need to have an "rc.local" file that sets them
or you need to do this manually every time you reboot the system.
I admit that I'm only using a single 10GigE card for my application --
streaming up to 4 channels at up to 25Msps
per channel.
But I can literally just let it run for days at a time without issue on
my particular computer.
