At 3 am the trx stopped again. This time it exited (itself) after logging large amounts of packet loss,

within 1 second or so....(as far back as the terminal history displays).

Restarting it signal came back within a few seconds.

UHD used: UHD_003.009.005-0-unknown installed with apt.

trx: osmo-trx-uhd_0.4.0.124.42c1_armhf.deb

It seems the interaction beween UHD and TRX is the problem, ( or the TRX itself ) since just rerunning

trx fixes everything, and the rest of the BTS components seem functionally intact.

Hmm, is the event code actually generated by the uhd driver? It looks like

the definition of EVENT_CODE_SEQ_ERROR that generates this log item comes

from include/uhd/types/metadata.hpp
