Hi,

i have upgraded my current lab setup to ubuntu 18.04 and UHD 3.13.0.1.
The eNodeB starts well when the PC was restarted or the freshly USB
cable plugged in. However, starting the a second time eNodeB I get
multiple UHD IO (30) errors
(https://files.ettus.com/manual/error_8h.html). Starting the eNodeB a
third time srsLTE aborts also with (Error opening RX stream: 30).

Best regards,
David
