Trakar Server on Digital Ocean reading too much data

I've been runnning traccar now for about a month with about 10 devices. It was all working fine until the server cpu was overloaded. I don't know why. Does anyone have a clue?

It usually runs at about 3%

Also the DISK I/O was reading 300mb/s (it's usually 50)

Which version are you using?

latest version

You should check what process uses the disk IO. My guess is that it's swap.

ok thank you
