For the past month or so I have been getting out of memory errors on my unraid server. Can someone assist with finding a way to getting this error resolved once and for all? I have a hunch it may be Nginx Proxy Manager in docker causing issues as I first noticed it when I deleted an entry and the memory errors popped up. My thoughts was to migrate to Traefik or some other proxy app but.. you know.. it's just a lot of work to redo and I've not had a chance. In the meantime, I'd love to know what is causing the out of memory issues.

Nginx is getting constantly killed for using a lot of RAM, that is also used by the GUI but it's not an issue normally, do you have anything else that uses it?
