My best guess is you have a log file that just keeps growing and growing because the flow never turns off to clear it out.

Find this log file and every once in a while in your loop, delete it or clear it out.

Unfortunately, I have no idea where this log file would be. I honestly don't know where to look beyond:
C:\Program Files (x86)\Power Automate Desktop

Good luck!

I would suggest you clear as many variables as you can during runtime, so you don't store a lot of information in them all the time. This consumes a lot of memory. Also, if you use Chrome in your flow, it might make sense to switch to Edge. Chrome is a monster when it comes to eating up memory.

If you have any less than 8GB of RAM, you should also get more installed, if possible. 8GB is the minimum. For a flow that should run infinitely, you would actually need more - I'm guessing at least 32GB.

And yet, you should still not expect it to run infinitely. It's not designed to be run this way, and it will consume loads and loads of resources. I assume the reason you are doing this is so that you don't need a paid Premium license, but really, at $15/month it's not really that expensive. I can't think of a process that wouldn't save you this much, but would still be worth automating.

Hi Agnius,
thanks for the advise! please check my below answer and question, thanks!
1. clear as many variables as you can during runtime - how to this?
2. we don't use UI interaction for this flow, we use the flow download file from SharePoint then insert into DB
3. the RMA is 64 G
4. we have Premium license, why I didn't use schedule Cloud to invoke Desktop flow is we use MFA to login the desktop flow running server, one step is use 'Duo Mobile'. someone need accept from 'Duo Mobile' when login.

To clear variables - simply have a step in your flow where you use Set variable to set as many of your runtime variables to blank values. Also use Clear list to clear list variables. Have as few of them as possible in general, and then also try to clear those you can.

If you have a Premium license, why don't you just use Windows Task Scheduler to schedule your flows?

If you need to use default values, simply set them in your flow and not use input variables at all.

Not as far as I know. If you don't want to hardcode them in PAD, put them in a text file and make the flow read the file.
