Hello,
I recently bought an EdgeRouter X and upgraded it to 1.9.0. Unfortunately, the router keeps crashing about once or twice a day with a fairly basic config. The configuration is based on the WAN+2LAN2 wizard with minimal modifications, one of them being enabling Smart Queue.
I've upgraded to 1.9.1alpha2 but the problem persists. I tried enabling netconsole and the built-in syslog server support and directing logs to a Raspberry Pi. Unfortunately, the syslog server logs nothing before the crash. The first log entries I can find (in /var/log/messages) look like post-crash entries:
Dec 4 17:15:33 ubnt ntpd[1241]: ntpd exiting on signal 15 Dec 4 17:15:35 ubnt ntpd[2894]: ntpd 4.2.6p2@1.2194-o Fri Jul 29 22:29:12 UTC 2016 (1) Dec 4 17:15:35 ubnt ntpd[2895]: proto: precision = 41.071 usec Dec 4 17:15:37 ubnt ntpd[2895]: ntpd exiting on signal 15 Dec 4 17:15:39 ubnt ntpd[2989]: ntpd 4.2.6p2@1.2194-o Fri Jul 29 22:29:12 UTC 2016 (1) Dec 4 17:15:39 ubnt ntpd[2990]: proto: precision = 48.286 usec
eth0 is connected to a cable modem and eth1-4 have various devices connected, including a UniFi AP and an UniFi Controller.
Config attached. The EdgeRouter was stable for about 4 days with Smart Queue disabled, but after I enabled Smart Queue, it crashed within about 24 hours. That makes me suspect Smart Queue.
