Crashes randomly. I get this from crashlytics and cannot reproduce on my own devices
I am getting the crashes too, any update about the issue?
Also getting a few production crash reports from Appcenter, anyone has any idea?
-[RCTSRWebSocket stream:handleEvent:]
RCTSRWebSocket.m, line 1349 SIGABRT
Wow, this issue is quite recent! I'm getting the same issue.

Might be useful to mention that I do not use the WebSocket from the React-Native API. I'm using the client of socket.io-client.
I'm seeing this same crash as well. I've caught the crash in the debugger a couple times after closing the laptop lid and then coming back later. I've only seen it happen in the simulator.
react-native-cli: 2.0.1
react-native: 0.53.0-rc.0
seeing this too on 0.57.7, using sockJS (which I believe will make use of RCTSRWebSocket)
This PR https://github.com/facebook/react-native/pull/22439 might fix this issue
Closing because aforementioned PR fixed other similar issues too: #21086, #6117. In case it still happens, please re-open.

I made a mistake!
React-native 0.57.7
Xcode 10.1
Long time no operation, and then automatically crashed. It happens on the simulator!

I got the same issue in my ios application when I created a release build and install on my device and found a crash after not operating the device for a long time blow is details
