Unknown Error while workflow execution

[Mustafa_Ali]

Hey,

I have made a workflow that gets trigger every 3 hours and takes approximately 15-20 min to execute completely. But since last one week it is hitting unknown error for all of its execution. I am also not to see the execution log of the workflow. How can I resolve this?

Hi @Mustafa_Ali, this could suggest your n8n instance crashes when executing the workflow, possibly because it runs out of available memory

Would you be able to reduce the amount of data being processed in each execution or split up your workflow into multiple sub-workflows to see if this improves the situation?

We had similar issues and could fix it by switching our n8n installation to using a worker. This reduced our load enormously. So I would agree, this could be some kind of memory or load issue. In our case, the load didn’t look like having a problem. But the worker was our solution and even increased performance.
