Memory leak right after opening IDE

[leonhh]

I just tested with beta-8 and it seems like there is some sort of memory leak with my project. When I use a newly created project this does not happen. It happens immediately when opening the IDE. It does seem to create a simulator but it keeps hanging on the build step and it consumes all available memory.

thanks for reporting. Is the provided list of hanging processes a result of you trying it multiple times, or it spawns processes like that with a single run. Also when you shut down VSCode do these processes stay active?

[leonhh]

Hi @kmagiera thanks for looking into it. So far RN IDE seems really promising!

The provided list of processes is the result of clicking "Open IDE Panel". So that would be a single run. After dismissing the IDE panel the processes will keep spawning. After closing VSCode the processes will stop spawning and they will automatically stop again.

This is after closing VSCode:

Would you be able to double click on any of these in activity monitor to see what's the parent process? The IDE doesn't launch react-native CLI commands at all, so this must be spawned by some other commands that we run

[kmagiera]

I checked on what could be spawning these commands, and it appears like this could be pod install process which handles outolinking. Have you maybe used the IDE to install Pods (there is a "fix" button in the diagnostics panel for that)

[leonhh]

No, I have not used the IDE to install pods. I already ran expo prebuild before starting the IDE. Pods are already installed. This issue also happens when all other plugins are disabled.

I just cloned the repo and will also try to dig a little deeper myself.

[leonhh]

Closing this for now as it seems to work fine in other projects and I could not reproduce it in a clean project.

@kmagiera @leonhh Hello Sir! I've been using the IDE, by the way, amazing.

However I'm seeing something quite similar still. After using it several times, I have to go to activity manager and kill tons of node processes that seem to spawn as a result of using it. This gets to a point where every start up it overloads memory if I don't do this.
