[USRP-users] GPSDO desynchronisation during Initialising

I have a issue with my X310 USRP (bought from National Instruments the model NI 2950). The GPSDO (LCXO BOM: 3.1, FW: 0.929a-1PPS, PN: 100) loses the synchronisation almost every time when the flow graph is started, just after the console outputs “Found an internal GPSDO. Initializing time to the internal GPSDO”.
It takes a variable time for the board_sensor to get locked again, somewhere between 10 seconds and 15 minutes. 
Did someone had the same issue or knows if it is a software/firmware/hardware problem of any idea how to fix it?
I use UHD 3.8.4.

Thank you.
