Gullik Webjorn gullik.webjorn at corevalue.seGentlemen, While upgrading to osmo-bts-trx_0.8.1.199.5c93_armhf.deb <http://download.opensuse.org/repositories/network:/osmocom:/nightly/Debian_9.0/armhf/osmo-bts-trx_0.8.1.199.5c93_armhf.deb> solved most of the problem, the main issue seems to remain. The latest version reduced failure rate from 1-3 / hour, to 18 hours, but did not eliminate the problem, i.e. a spinning trx-uhd.

Thu Dec 27 18:53:00 2018 DMAIN <0000> Transceiver.cpp:1005 [tid=3007431760] new latency: 7:33602 (underrun 6:1683350 vs 5:1683348) as you can see this is very similar to running osmo-bts-trx_0.8.1.194.8564_armhf.deb, but only happened after 18 hours seemingly stable. syslog says: Dec 27 18:53:37 localhost osmo-bts-trx[2166]: #033[0;m#033[1;33m<000b> trx_if.c:178 No satisfactory response from transceiver for phy0.0 (CMD POWEROFF) Dec 27 18:53:39 localhost osmo-bts-trx[2166]: #033[0;m#033[1;33m<000b> trx_if.c:178 No satisfactory response from transceiver for phy0.0 (CMD POWEROFF) Dec 27 18:53:41 localhost osmo-bts-trx[2166]: #033[0;m#033[1;33m<000b> trx_if.c:178 No satisfactory response from transceiver for phy0.0 (CMD POWEROFF) Dec 27 18:53:43 localhost osmo-bts-trx[2166]: #033[0;m#033[1;33m<000b> trx_if.c:178 No satisfactory response from transceiver for phy0.0 (CMD POWEROFF) so bts-trx and trx-uhd have lost synch with each other. Just restarting trx-uhd resolved the situation, if bts-trx had timed out, it would have restarted, and I assume the whole thing recovered. next time it stops, I will kill -9 bts-trx, it should restart auto, and I will see if it does not matter WHICH process is restarted, I earlier believed the problem was in the trx-uhd, but replacing bts-trx was the factor to go to "almost stable". I will report my findings, if you have any more intelligent suggestions to how to narrow this down, please go ahead.....
