"L" error code when using Ettus N310

Hi all,

I am using an Ettus N310 to transmit and receive signals. My goal is to receive four signals and transmit two - however, in this configuration my GNU Radio script throws "LLLLL" errors in the console. I have had success using the N310 in other configurations with no issue, such as receiving four signals or receiving two signals and transmitting two signals.

The only documentation I have seen on the "L" code is here, but it doesn't really clear anything up.

https://github.com/gnuradio/gnuradio/issues/3830

Tx: "Late data (arrived after indicated time)". Rx (RFNoC only?): "Late command (stream command arrived after indicated time)".

According to the documentation, I believe receiving four signals and transmitting two signals should be possible. Can anyone provide input as to what might be going on?

Thanks,

Chris
