Resolving the "Out of Memory" Issue for Browsers

My team is receiving reports that users are experiencing an "Out of Memory" error on their browser and slow loading times when they access one of our PowerApps applications.

The main data source for this application is a SharePoint list that currently has around 2.6k items. A second SharePoint list is used to store comments for each form that is processed, and this list currently has around 15.4k items. The main list is refreshed throughout the application frequently and stored in various collections that are based on the status of the forms. Additional collections are used to check for duplicates within the list during each step of the form's process. The comment list is only refreshed when a form is accessed.

This issue has not been reported for our other form processing applications, but our other applications have less items stored in their SharePoint lists. This has led us to believe that the larger quantity of items in this application's lists is causing the "Out of Memory" browser error and slow loading times that users are experiencing.

Are there any methods that can be used to resolve these issues if the SharePoint list’s increasing item quantity is causing these issues?
Thank you.

Hi @NikiJ ,

Regarding the issue that you mentioned, I think this issue related to your large quantity items of your SP List, and your PC's configuration.


When you run your canvas app, it would consume a lot memory resource in your PC (which is based on data source, controls, ... added in your canvas app). So please make sure you own enough memory to run your canvas app. Please close these unnecessary back-end process from your PC, then check if the issue is solved.


Also please check if your PC's configuration has meet the System requirements for running a canvas app:


In addition, please check and see if the Performance tips for running a canvas app could help in your scenario:

I have a similar issue.  I have a document library with only 81 items that has a custom Power Apps form associated with it.  81 items shouldn't be causing a memory issue.  Is there a better solution than the one listed above??
