Issue Description

Hello.

I use a GPS antenna connected to the GPS input of USRP b210 and locked correctly. I run epc and enb but after a while, eNB shows this error and death: [ERROR] [STREAMER] The receive packet handler caught a value exception. ValueError: bad vrt header or packet fragment [ERROR] [STREAMER] recv packet demuxer unexpected sid 0x15bfed7

This configuration is set in enb.conf device_args = type=b200,clock=gpsdo,otw_format=sc12,num_recv_frames=64,num_send_frames=64,master_clock_rate=15.36e6,time_alignment_calibration= gpsdo (I also have same problem with sc8 and sc16). Can anyone help me?

Setup Details

I installed srsRAN_4G in Ubuntu 22.04 on pc by this config: Intel(R) Core(TM) i7-7700K CPU @ 4.20GHz, 8 cores, 8G RAM. I use usrp b210 and uhd version 4.4.0

There's not enough info here for us to do any research. If possible, find a UHD-only way to reproduce this.
