<p>At 3 am the trx stopped again. This time it exited (itself) after
logging large amounts of packet loss,</p>
<p>within 1 second or so....(as far back as the terminal history
displays).</p>
<p>Restarting it signal came back within a few seconds.</p>
<p>UHD used: UHD_003.009.005-0-unknown installed with apt.</p>
<p>trx: osmo-trx-uhd_0.4.0.124.42c1_armhf.deb</p>
<p>It seems the interaction beween UHD and TRX is the problem, ( or
the TRX itself ) since just rerunning</p>
<p>trx fixes everything, and the rest of the BTS components seem
functionally intact.<br>
