iOS only FileLogger crash #147
Description
Hi. We often get a crash due to file logging on iOS only: Uncaught Kotlin exception: kotlinx.io.IOException: Failed to open /var/mobile/Containers/Data/Application/108A558C-60A9-4612-899B-2271BFDE71FF/Documents/Logs/log.txt with Too many open files
It seems that logging too fast can cause this crash. Also we've noticed that sometimes some logs are missing from the file although they show in Console. Again, this is strictly iOS issue. All good on Android.
NOTE that this is not a new issue. It happened in the previous versions as well; we started integrating since 1.3+ and we now use 1.5.0
Below the crash stack trace:
