Having memory problems, shut down everything I could. The web server is what I think is causing the memory issues. I ran it a long time yesterday checking temp every 2 seconds, may increase that a bit, but after several hours I started getting 500 errors and timeouts and eventually the web server wouldn't respond at all. My lcd display kept working so I know the program was still running and I have it blink and led too to show me it's still running.
I've gone from green to yellow to red when the web server I believe stops working. It also looks like the more browsers running the page the more memory it takes but not totally sure on that.
I'm wanting to setup a PID for some heaters but already having memory issues so not sure if it's going to be able to handle it and the temperature probes.
