cmd time errors with UHD USRP sink

[zhanght34]

I'm playing with gnuradio and an USRP X410 device.
I connect pc with USRP X410 by QFSP.I want to test how fast the QFSP port transfer rate is.
Then in gnuradio grc,i have connected two block:Sig Source and USRP Sink. Details as shown

When i run this grc,and set samp_ate to 30MHz，gnuradio printfs"cmd time errors".How to slove it?

I have the same issue. Did you ever get it solved?

We have too little data, so I'm closing this. In general, using the USRP Sink works with X410 and other devices.
