Server Version: 1.11.2, Platform: Spigot 1.11.2, OS: both MAC and PC, Java Version: 1.8
So I am building a server with a few friends, and last night we were building a few things and made a few tipped arrows with some slight potion effects while we were building a new dungeon for one of our maps. We logged off and I came on the next morning and relieved this message when I attempted to log on... (View First Screenshot)
My brother and I began researching to try and find the solution. We, of course, restarted the server by first stopping all actions and shutting it down and then restarting it. No success. We then figured that some player inventories might have been corrupted, so we deleted all player data. No success. The numbers didn't change at all. We then began removing worlds from the server file in hope to at least find where the problem was coming from. No success. I personally removed about 5 of the 18 worlds out of the file (the worlds we had been building in before) just in case they were corrupted somehow, but still no success. Minecraft itself isn't the problem, because we have taken one of the world files (without plugins or permissions or anything) and opened it in vanilla Minecraft and it worked like a charm. No chunks were glitching and nothing was lagging at all.
I asked a few friends who run servers of their own, and they told me it may be a plugin issue. So I removed all plugins from the server, and still no change. The problem says that the file it's talking about is too big and exceeds the max protocol amount. I have seen this before but everything the people suggested to try we have tried.
On the server console it registers that a player logs in, but then immediately leaves. (View Second Screenshot) We have tried transferring the files to a different computer, but that did nothing at all. Multiple players have logged in (they had logged off before in various different worlds) and they all get the exact same error message.
I also noticed something when we were researching others who had had this problem. The "max protocol" number it says is 2097152, and other people have encountered that message, and their says "Badly compressed packet - size 2198462 is larger than protocol maximum of 2097152." If you look at the first screenshot again, it says that the size 2703296 is larger than protocol. Whatever the problem is, it is 700,000 points over than the protocol max. Which goes to say that it is not just a small thing.
Does anyone have any idea what the problem might be?
Are one of your friends using any kind of cracked, hacked, or even optifine enhanced clients because it seems one of them if not all of you are sending the server invalid packets? Optifine wouldn't really do this but a hacked client could. Or more likely, some of your plug-ins may not be compatible with each other causing the server to mishandle its packets and go over its packet threshold. So you should triple check the compatibility of your plug-ins.
Try disabling your plugins one-by-one, it might be caused by faulty plugin.
I removed plugins one at a time and the numbers didn't change one bit. I tried that multiple times, and I even removed all of the plugins at one point and nothing changed at all... Weird right?

None that I know of. One person used optifine but that couldn't be causing 700,000 points of overload. And I am about 90% sure no one uses hacks or broken clients or anything like that on the server. As far as I know they use standard vanilla minecraft. Not even any modpacks or rps. There are a few conflicting plugins, but we have had conflicting plugins since day 1 and I have never seen this problem before. But, I still removed all the plugins at once, and the numbers didn't change at all. So I have no idea what the problem is.

Thank you for your time.
