Android device log shows reanimated related message every milisecond then crashes #1932

andreialecu · 2021-04-13T10:47:20Z

Description

Been troubleshooting some Android performance issues and crashes, and I noticed in the device log (using Flipper), that there's a message being logged every milisecond:

Not sure if this is normal or what is causing it, but it mentions reanimated.

Expected behavior

No log spam.

Actual behavior & steps to reproduce

See screenshot above

Package versions

React Native: 0.64
React Native Reanimated: 2.1.0

Affected platforms

Android

Issue validator

The issue is valid!

andreialecu · 2021-04-13T10:50:36Z

~~These could be related, as they appear to be logged immediately prior to the log spam mentioned above:~~

The app also crashes few seconds later.

Edit: It doesn't seem to be directly related. I was able to see the two separate log anomalies logged independently of one another. The warning in the screenshot above does not seem to cause the app to crash.

Also Flipper's Logs screen crashes because of the massive amount of logging, so I'm not sure yet what the actual crash is. I'll try to debug with Android Studio.

andreialecu · 2021-04-13T11:08:48Z

Even Android Studio has problems keeping up with the amount of log spam:

2021-04-13 14:07:44.624 15644-15644/? I/MessageQueue: searched 10000messages,recent msg is { when=-886ms callback=com.swmansion.reanimated.Scheduler$1 target=com.facebook.react.bridge.queue.MessageQueueThreadHandler }head message is { when=-1s444ms callback=com.swmansion.reanimated.Scheduler$1 target=com.facebook.react.bridge.queue.MessageQueueThreadHandler }
    
    logcat: Unexpected EOF!
    
    This means that either the device shut down, logd crashed, or this instance of logcat was unable to read log
    messages as quickly as they were being produced.
    
    If you have enabled significant logging, look into using the -G option to increase log buffer sizes.

andreialecu · 2021-04-13T11:14:29Z

After setting adb logcat -G 10M I was able to see the reason of the crash:

Seems that the OS just force closes it because it doesn't respond for 5 seconds.

Could you search for MessageQueue string in your app and your dependencies (outside of react-native package) sources?

Something like:

grep -r 'MessageQueue' --include='*.java' --exclude-dir='node_modules/react-native' .

in your project root.

andreialecu · 2021-04-13T12:27:42Z

Here's a repro:

https://github.com/andreialecu/rnctv-react-native-bare-test/tree/android-reanimated-crash
Run yarn android to run it, and press the blue button, then try swiping left/right to switch between tabs.

Notice that it only occurs on a physical Oppo A72 device (I don't have any other Android device to test). I wasn't able to get it to reproduce in the emulator. Might be related to #1912 which mentions Oppo as well.

andreialecu · 2021-04-13T12:30:27Z

@jakub-gonet I can't find anything relevant from that search. It reproduces with the repository I linked in the previous comment, so you could run your own search in it. But there are no other native dependencies except reanimated in the project.

Make sure to use the android-reanimated-crash branch.

The only other similar type of log that I can find is in this pastebin from 2019:
https://pastebin.com/mNyhtCqh

No idea what is logging it. I think it's related to doing sync work on the main thread, resulting in some sort of race condition.

andreialecu · 2021-04-13T13:10:30Z

One note about the repro: It initially did excessive work, trying to load 1000 images. This resulted in the same issue just by itself.

I pushed a commit to it to load less, then you can see the crash occur while swiping between tabs.

It's possible that react-native-collapsible-tab-view does something it shouldn't, but I don't think it should produce a hang/crash.

piaskowyk · 2021-04-14T14:45:55Z

Probably this issue is related with #1923

andreialecu · 2021-04-14T14:53:19Z

@piaskowyk do you have any information on why you think that?

I have just tried switching to reanimated 2.0.1 in the repro I linked above. The crash from #1923 does not happen with 2.0.1, but I can still reproduce the log spam even with that version.

andreialecu · 2021-04-14T15:02:30Z

Just a note: I'm definitely able to reproduce this on 2.0.1, seems #1842 is only part of 2.1.0.

I ran gradle clean and everything.

piaskowyk · 2021-04-14T15:04:19Z

Thanks for info. I will check this and let you know when I will know what happened.

andreialecu · 2021-04-14T15:45:30Z

So this is interesting, I switched from Hermes to JSC on 2.1.0 and tested the repro and the same logs have appeared, but this time the app wasn't force closed. It was responsive from time to time, but mostly it was hung. It would respond every few seconds or so for just one frame.

It then suddenly stopped the logs and the app became responsive. Notice the OpenGLRenderer log immediately after.

andreialecu · 2021-04-21T14:12:42Z

@piaskowyk just wondering, because you didn't mention it.

Were you able to actually reproduce this issue with my repro?

LadislavBohm · 2021-04-29T21:25:30Z

I am having the same issue on OnePlus device when switching between BottomTabs using react-navigation. When

start the animation with a button click
wait for animation to finish
navigate to another tab
go back to previous tab

App will hang and after few seconds crash.

@piaskowyk if this helps, it appears that this happens more frequently when the main JS thread has a lot of work to do.

In our app, we're using @formatjs Intl polyfills which are very slow. It can take 20ms to format a single date on a real android device using Hermes.

If we have a FlatList and each item formats a date, the bigger the list is, the faster this bug occurs with reanimated.

It looks like it might be triggered by some race condition.

Regardless, the repro I attached in my earlier comment does show the issue more consistently. In the real app it occurs more randomly.

An update on this.

After optimizing everything as much as possible and reducing JS thread cpu usage to very low levels this stopped happening even on the lower end device.

I'll keep it open because the repro above still shows it.
