Most of the time, my app is running at 10-20% CPU and under and using about 400 MB RAM (out of 1GB).
Tonight RAM started hitting 600MB, but CPU flew up to 70% and then eventually 100% crashing the app. I was handling more traffic than usual but it wasn’t that much more. Why did the CPU increase so quickly out of nowhere instead of increasing gradually as does the RAM?
Responses very much appreciated. Have a serious scaling problem on my hands now.
