Are you up to date on iOS 14.4 by the way? If not, try upgrading to that as a first step to tracking down the issue.
Also, iOS might be capturing your crashes in it’s Analytics dump. When Mosaic next crashes on your iPhone/iPad, from iOS’ Settings, go to [Privacy] → [Analytics & Improvements] → [Analytics Data], and from the search bar up top, type in the date of your crash in YYYY-MM-DD format (e.g. “2021-02-08”) and see what turns up. That file might be handy for dCS to track down any potential issue Mosaic might have.
By the way, what language is your iPhone/iPad set to if you don’t mind my asking?
Hi Anup!
No problem with your question about language!
I have the file you requested but the platform here tells me that the file is not authorized
because of the extension. How I can manage this thing?
Hey Stefano, those Analytics dumps are usually plain text files that you should be able to view from the iPhone itself. Note: As it usually contains private information, be careful not to send it out to anyone randomly , best to scan through it yourself for clues as to whats causing Mosaic to crash.
Here’s an example of a crash log that iOS generates on its own (a simulated crash log). The top area will usually show whats causing the App to crash, I’ve highlighted in red, see if you can find some clues in your crash logs.
The exception notification suggests the App was killed by the iOS watchdog process due to the App being “unresponsive”. One of the primary reasons for an App being unresponsive is synchronous networking related, so, if this is the log from Mosaic crashing, looks like it might actually be networking related after all (as Pete and Carsten suggested!! )
Stefano, I’ll take a closer look at your FRITZ!Box 7330 to see if theres any clues. I wonder whats changed (besides iOS?) from when Mosaic was working just fine for you . Do you have any other WiFi access points you can try with by any chance?
Thanks Anupc.
I am sure.
Nothing is changed in os and even in my network. I remember that I was using the app on my sofà listening music. I remember that for several minutes all was ok. Sometime I switched from Roon to Mosaic and vice versa.
It was when I switched to Mosaic from Roon that I have seen Mosaic freeze and than suddenly shutting off. Since that Moment The problem has remains. No I don’t have any other access point.
As at this point we seem to be suspecting some kind of network issue I am wondering if the Roon/Mosaic switch just happened to occur coincidentally with some other change taking place which was perhaps invisible to you.
For example, AVM installs updates to Fritz!box from time to time and the change is not necessarily visible to the user unless you interrogate the firmware. Could this have happened and have changed a network setting causing your issue?
Anup:
Would it help if Stefano posted ( or PM’d to you) some screenshots of the Fritz!box network settings?
I‘m not sure as not being an expert, but could it be related to 7330’s port management? As far as i‘m informed in some routers you have to enable the port for UPNP. Must be somewhere in the routers menue, possibly home network —> network —> enable port for UPnP or something similar (i excuse for not speaking much italian, although i fell in love with Your country many years ago).
Whoops!! I somehow missed this … thats a deadlock condition associated with the App holding a file/database lock during suspension, and iOS killed the App as a consequence.
Stefano, this looks like maybe an iOS related issue [rather] than networking. Here’s a suggestion;
Can’t think of anything else to try at this point.
(Although, if you use a Mac, you could try connecting your iPhone to it and launching the console to see what happens live as the App crashes, but thats really getting into the weeds )
HI Anup.
I’ll try as soon as i can.
In the meanwhile I have installed Mosaic on an Android device.
Same problem.
It took just 4 or 5 seconds more to crash.
This is very strange behaviour. I haven’t come across this before - we haven’t been able to replicate this issue and haven’t had any other reports of the same problem, so currently working with our R&D department to get this resolved.
I’ll update here if there as soon as I have anything further.
It is highly unlikely that the issue is related to the Bartók’s software version - from what you have said above the unit has been updated to version 1.1.1, so this should not be causing a problem.
For reference, you can update a Bartók without using Mosaic by navigating to the Bartók’s IP address in a web browser, clicking on Device Settings, then within the Internet Update section clicking on Check for update. The IP address can be found by opening the Unit Status menu page on the front panel of the unit (press the Menu button three times).
In this case I would expect checking for a new update to report back “No update available” however.
Hi James
I didn’t want to mean that the problem is on Bartok.
I was simply worried how to update the machine in future. Your software update is a high value feature and I don’t want to miss.
