Like @darcilicious mentioned the issue is likely on the PMS side and we’d need to take a look at your PMS logs to see exactly what is crashing. The Sonos logs don’t show much other than timeouts, presumably when PMS has crashed.
I ran Sonos app (software on Windows) located on the same machine as PMS. While browsing music it crashed. I pulled the logs after restarting PMS. Logs are attached. Thank you!
There was a request for all tracks in a library and that would have exhausted the server resources and would have run out of memory and crash
Jun 26, 2018 17:44:06.397 [9196] DEBUG - Request: [52.90.142.21:60502 (WAN)] GET /library/sections/1/all?type=9&sort=addedAt%3Adesc (5 live) TLS Signed-in Token (guydicara)
Jun 26, 2018 17:44:07.813 [9196] DEBUG - It took 1234.375000 ms to retrieve 15475 items.
If you enable verbose logging as well, I can confirm if the application making these requests was paging the requests (ie 100 or 200 at a time)
This sort of problem was also noticed in Plex Web - but only when doing a multi-select of tracks from a massive library
Thanks for providing the logs…turns out pagination was not actually working like we thought it was. An update has gone out that should fix the issues. Please give it a try and let us know!
