@noris I was reviewing the syslog on the core from the time of the disconnect and the following entries are recorded. I search the Roon Community forums and it appears that I am not the only person reporting these symptoms along with similar log entries.

That’s interesting… With your find I have been looking at my syslog, too, and there is exactly the same log entries today at 05:53:17 am, when Roon server was not being in use and therefore I didn’t even realize that such an event had occurred again.

@moderators this thread is up and running can you seperate or reopen.

[Robem]

I see that @nuwriy mentions in this thread that diagnostics were going to be enabled for @Lawrence_Klein - did that ever get enabled and is there anything to see in the results?

[Andreas_Philipp1]

@Robem

is there anything to see in the results?

If @Lawrence_Klein’s case is similar to ours and Roon Appliance SIGSEGVs probably there is nothing to see in the Roon logs. I have been looking at my Roon logs, and from the moment it gets a SIGSEGV to the moment it starts up again there is nothing in the logs. There doesn’t seem to be an independent Logger process.

As we agree that this behavior is something recent, it seems as if some update to 20.04 would have surfaced this problem. Or it could have been Roon’s 667 build update from mid-October. For me it’s no big thing as I am able to play music all day long for days on a row and only have seen the interruption a couple of times. From looking at the logs it is clear though that it happens more often than I experience.

As we agree that this behavior is something recent, it seems as if some update to 20.04 would have surfaced this problem. Or it could have been Roon’s 667 build update from mid-October.

Absolutely agree, I am not sure whether it was the update to 20.04 or the one to 667 because they both happened at around the same time but everything was working seamlessly prior to that. The symptoms that Lawrence describes do appear to be the same but they may be unrelated.

I had another occurrence of this this morning - 06:28 Pacific - music stopped playing, remote lost connectivity and the same syslog and apport entries as before. I was playing “(I Don’t Want to Destroy) Our Beautiful Thing” by David J from a local file.

[Andreas_Philipp1]

I just installed the latest stable low-latency kernel from the 5.6 branch (5.6.17), just to see how things work out on a more recent kernel. If there is a problem with the 667 build’s mono runtime, I’d expect to see the same SIGSEGV events to occur.

[xxx (Banned - toxicity)]

Don’t know if all the problems in this thread are occurring to folks who are running RoonServer, but I had nothing but trouble with RoonServer.

Maybe try running full Roon as a test?

[Andreas_Philipp1]

This is on Ubuntu Linux - no full Roon available for Linux.

[xxx (Banned - toxicity)]

oops

[Andreas_Philipp1]

Just saw a thread were someone experienced similar SIGSEGV behavior after the 667 upgrade, but with the core running on a QNAP… which is Linux as well, after all.

System is crashing/restarting frequently since update to build 667

Core Machine (Operating system/System info/Roon build number) QNAP TS-473, AMD R-Serie RX-421ND Quad-Core 2,1 GHz CPU, 20GB RAM, running QTS 4.4.3, Roon Database on SSD (using 10.6GB out of 400GB). Roon Version 1.7 (build 667), QPKG-Version 2020-07-15 Media Library on NAS (around 57,000 tracks) Qobuz Studio Sublime Subscription Network Details (Including networking gear model/manufacturer and if on WiFi/Ethernet) Unifi Managed Switch, Unifi AP-AC PROs, HP ProCurve Switches Audio Devices…

[Robem]

Just an update to keep documented facts current, In the past day or so I have performed a dist-upgrade to Ubuntu 5.4.0-56.62-generic 5.4.73 - the symptoms are still being experienced since this action.

[Andreas_Philipp1]

In my logs I see another SIGSEGV occurrence today 06:15 am, without streaming at the moment. If these events were hourly or more often it would drive me crazy… and there’s no response by Roon support, even when other users experience the same. As it is, I can use Roon all day long with no problems, but something is not right.

[Robem]

I can also deal with once a day and not grumble too much about it. Reflecting back though, my original post from last week was started because I was experiencing disconnects multiple times in the course of an evening. Sometimes it would be multiple times listening to just one album. I disabled IGMP snooping and for a few days I thought that had resolved the issue, but after extended testing it became apparent there was still a problem. I wonder if I had multiple things going on? I might re-enable IGMP snooping this evening and see if I return the original state with more frequent disconnects and then analyze the log files.

[Robem]

I also want to say that I’m a little frustrated with the lack of response from @support too.

[Lawrence_Klein]

My drops are back to at least every hour or two, FWIW…
