Hi @Martin_Forster, this seems rather unusual. Are you by any chance looking at multiple threads of the same process? If you are using htop for example, you might want to enter uppercase H to show only the main process rather than each thread.

For example, when running docker run -it --rm -e EXECUTIONS_PROCESS=main -p 5678:5678 n8nio/n8n:0.222.1 this would be the default htop output (filtered for n8n):

This would be the same machine after pressing H:

Instead of the above you might find it easier to use docker ps:
