Memory-leaks

[aminpaks]

I changed two lines in your example and run it. After about 30,000 actions app accumulates up to 300MB memory and crashes.

These are steps to reproduce this issue:

1. Update addTicket in animal component to, this code simulates dispatching many actions to observe the issue easier:

   addTicket = () => {
   for (let i = 0; i < 10000; i++) {
     setTimeout(() => this.subStore.dispatch({ type: 'ADD_TICKET' }), 1);
   }
   }

2. Remove the createLogger and devTools enhancer from store/module:

   // Tell Redux about our reducers and epics. If the Redux DevTools
   // chrome extension is available in the browser, tell Redux about
   // it too.
   store.configureStore(
     rootReducer,
     {},
     [ ...rootEpics.createEpics() ]);

3. Run the app yarn start

4. Click on + to start the process: this will dispatch 10000 actions and update the UI.

5. Observe how app crashes after a few times clicking on the plus

You may check the memory in Chrome devTools too.

Hey - looking into it now. Please understand that I don't get to everything immediately.

I've reproduced the issue and confirmed that your fix works. Thanks, nice catch!

I also took the liberty of creating a PR with from your fork, here: https://github.com/angular-redux/store/pull/409. There are a couple of minor cleanup items after which I'd be happy to merge it.

I cleaned up the PR and merged it. The fix has been released in @angular-redux/store 6.4.1.
