I also asked Chris (xF4m3) about his opinion and he recognized a 10 minute spike pattern in the first graph from today. Is there anything running every 10 minutes (600 seconds)? :timer:
ClearLagg is set to run every 600 seconds, which explains why the CPU usage gradually goes up until the next ClearLagg schedule is ran. I might decrease the tolerance of server TPS drops to help prevent this without making the schedule too frequent for the players.
