Good afternoon,
For a few days now, when executing the workflow I have had problems since the process completely collapses and keeps processing all the time but does not process anything. It’s like it keeps the order to process but it doesn’t process and it gets bugged. In order to execute the workflow I have to execute the last module to execute the previous modules and see if the workflow works for me. This happens to me with all workflows and I don’t understand why this error occurs.
It looks like your topic is missing some important information. Could you provide the following if applicable.
Hi @Juan_Manuel_Narvaez ,
Welcome to the community!!
Do you get any error message at all?
And are you running n8n on a self-hosted instance? What’s your set up like? What verison are you on? 
Hello, the problem is that when I execute the workflow, it does not execute it, it stays in a loop in which it does nothing and when I try to stop the process I get an error that it is not possible to stop and it shows a message “Problem Stopping Execution : Only running or waiting execution to can be stop 285 is currently canceled”
I wonder if this has to do with the instance’s memory.
When the usage is too high it can sometimes block the UI from showing what is actually happening in the backend.
Does this workflow trigger a lot in a short period of time? And/or does it process a large data set?
I’d recommend taking a look at this documentation: Memory-related errors | n8n Docs
