The Great Cow crash of 2013

[Explodingboxes]

since i cant log in due to some unspecified error that crashes the server i will try and give kommy some info about where the crash is at
X = -8213
Y = around 64
Z = -3726

the cows were first noticed at around 6:54 PM with this
[06:54.46] <@MCJbot> ({Police}graystan21) um, i think there are about 3000 cows in that one spot

I have no idea whats wrong with that location or why but that is where i am when i log in and crash the server.

if anyone else has anything they could add about this like a screenshot that would be good.

I went there when PMB and Count were there earlier. It dropped me to 1 FPS. Miniguns apparently has better specs than I do and he was dropped as well. There is an entity count there of 3100.

I think part of the problem is not merely that there are so many cows, but that they're in the space of one block, and therefore are constantly colliding with each other..


Tl;Dr: the cows need to die.

This is the story. I was on around during midday (PST) and everything was fine. I had time to build some stuff and work on my firework room. I then started to work on a firework launcher in the jungle next to my house. When I got back my main house, my frames dropped to 1-2 fps. I thought it was something with my client/connection so I decided to get off and hope it would sort itself out. I got back on at the time boxes stated and was still having the problem. Still thinking it was odd and still client side I tried to deal with it. I then had to tp bally to show him something at one of my other houses and my fps shot back up to normal. This made me realize that it had to be entity related. I then went back to the jungle (through the /home command) and started to walk down the track I made to get to it easily w/o using /home. My frames dropped back down to 0-2 fps and then I saw at the end of the track about 3000 entities in the form of cows in mine carts. This is when a group of people helped to clear the problem as fast as we could. Some bug happened that one cow traveled into a cart and then duplicated over and over again.

We were not able to find what was wrong so kommy had to do a slight rollback so if you are missing anything just tell a staff member and they will try and fix it for you.

Yea... that whole area was like bermuda triangle. Just flying over or next to the area was crashing the server. Guess multiple chunks got corrupted somehow
By the way thanks again guys for helping me narrow it down and fix it.

Crap... while dealing with this crash I updated some plugins but messed up dynmap. Will try to fix it tonight or tomorrow morning
