I've been running into this error across several of my workflows this week:
"Workflow did not finish, possible out-of-memory issue"
For some executions, retrying works fine. But for 2 of my workflows, n8n sent me an email saying they were automatically deactivated due to repeated crashes — which means I have to manually go in and reactivate them each time.
I'm on n8n Cloud version 1.123.33.
After some research, I understand this happens when an execution exceeds the memory available to the instance, and that on Cloud the main options are to upgrade to a larger plan or reduce memory usage in the workflow itself (e.g. processing data in smaller batches, avoiding the Code node, splitting into sub-workflows).
That said, I haven't changed anything in my workflows recently — they were running fine before this week. Has anyone else seen a spike in this error lately? And has anyone found a reliable fix without needing to upgrade their plan?
Any help appreciated!
