Hi @jmvdv,

I know it’s been a while since we spoke about this issue, but has there been any change to this behavior with the new release in Roon?

We have been internally discussing iOS crashes and in at least one of the reports, we’re seeing the iOS device run out of RAM resources.

If this behavior is still ongoing, I was wondering if it could be possible for you to access your iOS console logs, reproduce this issue and send us a set?

Thank you!

Hi @noris,

Hi @noris,

So it seems memory is also a problem on my device. Think it happens when i scroll through lots of images too much is stored in RAM. It’s as if they don’t get removed from memory.

Thanks.

Hi @jmvdv,

Thanks for the console snippet! This trace looks a bit different than the one’s we’ve received so far, can I please ask you to upload the full Console log and send me a link (with the info leading up to the memorystatus: killing_specific_process)?

The image is a good theory, but we are also taking a look to see if the iPhone queue screen could be a cause, what is the amount of items in the iPhone’s queue when this issue occurs?

You mean the running app’s? Or the Roon queue?

Hi @jmvdv,

I mean the track/album queue from inside the Roon app.

I’ll check tomorrow, got a large history in the queue and scrolling through it caused the same issue. Will also send the logs.

Allright @noris, it still happens with empty queue. Got two log sets for you until the crash (and a minute before) with everything happening on my phone:

  1. Scrolling through a very large queue history:

  2. Scrolling through all my albums with an empty queue history and nothing playing:

  3. Again scrolling through all my albums with an empty queue history and nothing playing and logs filtered on keyword “roon”:

And number 4:

Started to crash while doing nothing, again connected to my Macbook and here’s the console for multiple crashes filtered on “roon”. During al these crashes the iPhone was running hot:

Hope this is enough. Let me know.

Update:

When I clear the image cache (settings > setup) on my iPhone I can scroll through my whole collection (1500+ albums) again without crashing after every 25-50 albums (when I start Roon again after crashing it’s scrolled back to top… the horror! :wink:).

Curious when it will start crashing again. Keep you posted.

Since emptying queue AND emptying image cache 5 days ago (previous comment) I had no more crashed…

Hi @jmvdv,

Thanks for sending those logs over, I have forwarded them to QA for closer inspection.
Since clearing out the queue and the image cache last week, has your iPhone still been stable?

Yes it is.

Hi @jmvdv,

I’ve been discussing this issue further with QA and they have a few questions to clarify the timeline of what you did to resolve this behavior, can you please let me know:

  1. After clearing the image cache and the queue, did you also reboot the phone or reinstall the Roon app on the iPhone or as soon as your cleared both of these out the app stopped crashing?

  2. How big was the queue screen prior to you clearing it out? Do you recall the approximate number of items in the queue?

  1. No
  2. Wouldn’t know… sorry
