Diagnostics from Roon ARC show regular backgrounded processes failing in the app due to low memory on the iPhone. There are two possibilities weāll need to investigate:
There is an open ticket, as Iāve mentioned, into a potential memory leak or feedback cycle that can occur with larger databases that should otherwise be within the available capacity of contemporary major market phones. In these cases, the resources available to ARC from the phone donāt meet the appās ballooning requirements, and key processes begin to fail, including diagnostic logging. However, the key diagnostic traces associated with this potential memory leak are not present in your logs, so thereās a second and more likely possibility.
What other apps are taxing the phoneās available resources when you encounter network failures in ARC? When you experience freezing and crashing, have you been playing local files, streaming, or both?
ARC will cache certain data in order to perform well during periods of low or transitioning connectivity. Reinstalling the app will clear this cache, relieving memory pressure. Logs from today show that memory pressure returns within about forty-five minutes, as youāve reported. Are you downloading local files during this time?
Specifically, out-of-memory errors begin to crop up when the phone requests metadata from Roonās servers. This is an example of how a large volume of local tracks stored on the phone can sometimes interfere with processes within ARC even if the phone has sufficient storage to maintain the files; additional files within a database can exponentially increase the network load on ARC, triggering these errors when memory seems available.
Weāll certainly pass this along to the team, and weāre working to streamline the update process. Feel free to post in Feedback if youād like to maximize the impact, as the team frequently reads that section. Thank you!
I am using Roon ARC as a streaming service. I have no dowloaded local music files on my iPhone. During my tests I tried to play music stored on my NAS and managed by my Roon Core. I do not used content from Tidal (Streaming with the Tidal app on my iPhone is problemless). I can not answer the first question about the resources. I think there is nothing special: MS Teams, MS Outlook, Apple Mail, Telegram, Signal.
no
How can we narrow down this issue? Can I help any further?
Thanks for the clarification. In that case, weāll need to take the investigation deeper on our end, as these symptoms are unique. Since weāve begun this thread, have you experienced any broader network issues in Roon Remote outside of ARC?
Weāll sync internally today and let you know what the team finds. I appreciate your patience so far!
Roon Remote (Control Point) runs without any problems on my iPhone and on my iPad.
From my perspective there are no network issue: Roon ARC connects every time to my Core (on WiFi and mobile network). Freezes occur when I navigate in the app, even without streaming/playing music.
Success!
I was able to use Roon ARC during the weekend without any problems.
Tested on site with WiFi and outside with LTE. Even in the car (fast driving on the Autobahn) was no problem.
