So I have a private server running (On my own physical server). It is running Minecraft 1.7.10 Modded. The modpack is Space Astronomy, albeit with added mods onto it. It's not a big server, only like 6 people play on it not more. I can't determine the cause, but at some point the server starts lagging and get progressively worse & worse until I restart the server and cycles again.
Since it was getting worse even though nobody was online, my first assumptions was that it was something that was chunk loaded. So I tried looking around everything that was chunk loaded but couldn't find anything that can be the cause.
I checked entity number, it seemed like a normal number so definitely not entity. After that, I really don't know what else to check. It's to the point the TPS is less than 2 and the past hours of my logs looks like this (As you can see, getting progressively worse.): https://pastebin.com/9JbC8WBg
I have installed Opis to try to find the cause but it isn't helping me much as I do not really know how to use it at all.
Does anyone have any idea on how I could find the cause of this ?
I doubt it's the hardware of the server itself as it is made to handle heavy load specifically for servers. I had it running for way more demanding things than that without problems.
Would anyone know how to be able to find what is causing the TPS slowdown? I have access to the console, being able to install mods, op, and of course, seeing / modifying the files so that's not an issue. I've also installed Opis so maybe we could use that too. I'm really out of idea on how to find what is causing it so I'd need some help please. Thanks !
Nah it's not that, it's just that it was in the middle of the log. After all, it's just autosave. (And it doesn't show in the console for some reason, only in the log).
There doesn't seems to be any issue with other modpack. And it wasn't doing that at the beginning when we first started the server and for a few days. I suspect someone placed something or activated a thing and that thing is causing the lag, but I can't find t.
