Published automations hanging in the queue. not executing

Describe the problem/error/question

My automations are just hanging in the queue. They’re never executing. They’re in the queue for hours. There are no other executions running. I haven’t exceeded the concurrent limit or my execution limit. I tried unpublishing and republishing my workflows. Not sure what’s happening.

It seems like there may be a memory leak because suddenly my entire instance will go offline even during simple manual executions.

What is the error message (if any)?

None

I also face the same issue and I tell you it really stuck for hours.

From what I observed this happens every time n8n cloud have new pending updates. And it disappear when you update to latest version. Quite a short term solution. But in any case, if you have any another solution please let me know. Thanks
