App crashes after 20s without any output

escamoteur · November 11, 2024, 9:22pm

After a pretty big refactoring of our app ND our backend API I’m currently with the problem that the app just terminates with a “connection list to device” on the android emulator.
No exception, no log messages. Also nothing reaches Sentry. Unfortunately I cannot run it with brek on all exceptions because of this bug in the Dart network layer OS Error: No address associated with hostname, errno = 7 · Issue #54580 · dart-lang/sdk · GitHub

I tried to run it with active memory monitor but couldn’t see any dramatic changes there.
Any idea what I could try to get more information what’s going on?

Maybe with flutter run -v you can see more interesting logs

I tried but that only increases the logs while building not what you get during execution

ok, I now get sometimes the same output as this issue here

## Steps to Reproduce 1. Load a text file of at least 3 megabytes. 2. Convert to String 3. Execute textPainter.layout() 4. Execute textPainter.computeLineMetrics() 5. do something **Expected results:** A problem occurs in steps 3 and 4. It should go to the next step, but it is either fatal or lost connection to device. **Actual results:** ``` I/scudo (15287): Scudo OOM: The process has exhausted 256M for size class 2096.
