So we are hosting an earth server (I am currently a moderator and our Owner is very stressed so ive come here to try for help) and everything has fallen apart on its own. We would occasionally get waves of lag with tps dropping down to ~12 then back up to ~20 over a few minutes without anything out of the ordinary happening. We average 20 players and tps averages 17-18 at these times but then a few days ago it started to break. The lag started growing and average tps dropping and today its just dead. If we boot the server its a maximum of 6 tps and towny decided to completely delete a nation and all of its towns after forcing some towns to join it (some were even in a nation already) But overall everything has collapsed and we have no idea why, its been on and off for a few days and we have tried disabling plugins, rolling back, killing mobs, upgrading. All to no avail, so there is clearly a deeper issue here.
Our host is pebblehost I believe and we are looking into switching after we fix this.
And just now we purchased 6 more gb of ram and its gone up to 12 tps with 7 players
