Description

I will conduct more investigation to obtain some more solid info on this one, but so far I can only report high memory usage/leak when an RSOD is encountered in a RN project whilst Remote Debug was enabled - A RSOD occurred while my machine was unattended, on my return i found the attached usage (and a hot, loud MacBook! 😛) only affects iOS.

The project is a boilerplate I'm working on and is currently a testbed for some UX work - there are no debugging tools installed in it, only apollo-client and native-base. The same behaviour seems to occur in an independent project, and the error has been encountered on colleagues' machines.

Reproducible Demo

Have a component throw an error on render to trigger RSOD and leave for a while. Memory usage rapidly goes up. Seems to only happen when chrome debugger is attached.

More details to follow after investigating some more.

Hello,
Not got round to providing more issues but can confirm this behaviour does seem to still occur.

Reproduce - react native init -> throw an error in first render -> leave on RSOD and monitor resource usage

Hello there 👋 this issue seems to have been inactive for the past few weeks. Because of this, it's likely that the issue is not a high priority anymore or it has been solved by OP; for these reasons, we'll close it.

But please, if it's actually still an issue with 0.59 please comment below and we can reopen it or please send us a Pull Request with a fix 😊

@kelset this is super old but I just experienced this and @Salakar mentioned it to me today as well. This is with react-native 0.59.9

reproduction is to run a react-native app in an iOS simulator, chuck an error that causes an RSOD / redbox / error screen then...wait. For me after just a couple hours I had about 30GB being used (!)

[anthonyhumphreys]

Yep same here. Those are the exact repro steps. I’d send some dumps etc but my main machine is out of action at the moment Get Outlook for iOS<https://aka.ms/o0ukef>

Oh, interesting!

Thanks for the update, let's reopen this.

So this wasn't happening with 0.59.8? I can't really see any commits that I have cherrypicked for 0.59.9 that could be related to this: https://github.com/facebook/react-native/commits/0.59-stable

[anthonyhumphreys]

Not really sure! Will do some testing when I get a sec but I’m fairly sure it’s been an issue for a few versions now, think it’s just an evasive one. Get Outlook for iOS<https://aka.ms/o0ukef>

Oh ok - any chance you can do your testing against 0.60 rc too?

[anthonyhumphreys]

[anthonyhumphreys]

Hi @kelset i'm slowly putting together some tests in here: https://github.com/anthonyhumphreys/rsod-tests - should have a few more bits in there this evening. Apologies for the delay in getting this to you.
