Hello dear Umbrel community,
My node hardware is:
-RB pi 4 (4GB)
-SSD 2 TB
I’ve noticed that ~2-3 days after installing several apps in my Umbrel node (BTC explorer, Mempool, Blue Wallet or more) I can’t access my Umbrel Dashboard (please see image below in which the loading bar is frozen)
If I use the command: sudo reboot, it will temporarily solve the problem for ~2-3 days, but after that period of time the same problem comes back.
I tried using the following command to solve this issue:
sudo systemctl stop umbrel-startup && sudo rm -rf ~/umbrel/lnd/!(lnd.conf) && sudo rm -f ~/umbrel/db/user.json && sudo rm -f ~/umbrel/db/umbrel-seed/seed && sudo systemctl start umbrel-startup
However, this command, as you know, deletes all apps and restricts me to have LN channels up all the time. And even doing this, installing the apps again will result in the same problem.
Here are the Umbrel Logs I got just when my node crashes, which occurs ~1-2 days after installing the apps.

I believe this issue might be related to RAM limitations of my RB pi 4 (only 4 GB), as it’s been very difficult to find 8GB ones these days.
Dear developers @DarthCoin & @louneskmt, is it possible to use a Swap File on the SSD to have more RAM available? Do you think this might help to solve this issue for those Users that do not count with more RAM? If so, could you please kindly indicate how we can do so?
I’d greatly appreciate your help on this.
