Description

Facing Memory Leak with React Native app integrated with existing native app.

I am currently on React Native 0.71.1 and tried to update to React Native 0.74.2.After upgrade facing memory leak. Memory usage keeps on increasing. With version 0.72 also there is no leak faced. But from version 0.73 facing memory leak.

Following this react native callstack brownfield architecture to load react native inside existing app as we have multiple entry points from native app to load react native in Fragment and also in Activity.

3. Try to open the example kotlin app
4. Open profiler from android studio

We are facing the same issue since 0.73.0. do we have any solution to this?

I am currently on React Native 0.71.1 and tried to update to React Native 0.74.2.After upgrade facing memory leak. Memory usage keeps on increasing. With version 0.72 also there is no leak faced. But from version 0.73 facing memory leak.

Can you try to update incrementally (first to 0.72 and then 0.73) and mention where you notice this regression?

Facing this issue from 0.73 version. 72.x works fine
