Troubleshooting performance spikes and script-induced app restarts on Cloudron?

[asil87]

I've been using Cloudron for a while now to manage a handful of production apps (mostly Nextcloud and a few custom LAMP instances), and for the most part, it’s been incredibly stable. However, I’ve recently run into a strange issue where specific background execution tasks seem to be causing my apps to hit their OOM (Out of Memory) limits and restart unexpectedly. It’s particularly frustrating because the RAM usage doesn't look that high in the dashboard graphs, but the "Events" log shows the app being killed right when my external automation kicks in.

I’ve already tried bumping up the memory limit in the app settings, but it feels like there’s a conflict between the Cloudron supervisor and how I'm handling these script injections. I actually tried a roblox modified approach to my execution flow to see if a more modular script handler would lower the overhead, but I’m still seeing these intermittent "heartbeat" failures during the handshake process.

Has anyone else here dealt with apps restarting due to external script calls or automated cron tasks? I’m trying to figure out if I need to move this logic into a separate worker container or if there’s a way to tune the internal OOM killer to be less aggressive during peak execution windows. I’d really appreciate any advice on how to keep the environment from crashing whenever the background task load spikes, as it’s making my automated backups and data syncs a bit of a gamble.

Not knowing what your scripts do, it's difficult.

If they do many things, can you slow them down and serialize them or chunk them into smaller pieces that need less memory to run?
