Describe the problem/error/question
n8n container is crashing and either restarts after few minutes or gives Bad Gateway error and requires a backup restore to starts working again.
I am guessing that some workflow causes a crash, but I can’t figure out which one.
What is the error message (if any)?
Please share your workflow
(Select the nodes on your canvas and use the keyboard shortcuts CMD+C/CTRL+C and CMD+V/CTRL+V to copy and paste the workflow.)
Share the output returned by the last node

That error would suggest a memory limit issue, It would be worth turning disabling all of your workflows and enabling them one at a time to work out which one is causing the issue.
That error should not require a restore to bring it back online again unless maybe the disk space is full.
--max-old-space-size=SIZE option. I’ve described this a while back over here, the page also has some additional suggestions on dealing with memory limitations.
