usrp x310

[xfx5636]

I use LabVIEW 2017 and USRP driver 2017,the device is USRP x310. I programed a project use Labview for usrp N210,now I want to apply my code for x310，but it appears error in Fig 1.It can run in the one shot way,when you stop it, the receiver can't run second time, must stop the transmission part，and click the run again,then start the receiver in one shot.I guess it is possible that the buffer is not released.Is that true and how can I fix it?Thank you for your help.
