server crashes when 2 players are logged in

soo i have this weird problem with my server and i dont know why it is happening, i have downloaded and put chunkload plugin (i said that plguin because the problems have started to happen after i put it it my server) and i downloaded it because i thought that it will keep chunks loaded if i go far away (i needed this because i was trying to film a video to advertise my server)
and it said that i have to put a region on selected chunks and i did it and restarted my server and then problems started happening,i first thought it was my crappy internet but i then i tried with my mobile with a different account and it crashed my server. i also tried to download and put it in singleplayer ad delete 2 files and it should work but didint for me and it worked for some people where i read it, and i tried to put a different map and it still did the same thing .i really dont know what to write anymore to help someone figure this out... please help someone i need help as fast as possible!! :/

 

You could have corrupted your map. You also could just have to find another plugin because it sounds like that one could have some issues.

 

Server Log please.
Also, make sure you're using CraftBukkit and not another unofficial, unsupported version.
Some of them had a critical bug/logic bomb in them yesterday and caused a mayor outage for many servers.

 

here is the log this one was in the latest.log http://pastebin.com/uNKUQ16F and i am using craftbukkit, it worked normally and the server was running for about a month now, it stopped working after i put chunkloader in plugins, also i dont know if this helps but i have my server hosted by some company,and when i look in doshboard under hearth rate it goes way beyond the green area, the green area is like a 1000 and it it like that when 1 player joins but when the other joins it goes to 12000-16000 and beyond that it would probably keep raising if the server didint crash

 

Hi I have this same problem.

Well, I don't know where to start:
1. You are NOT running CraftBukkit, you're running Spigot.

2. You're running in Offline-Mode
3. You're running several outdated plugins
4. You messed up some .yml files
5. You're missing some dependencys for some of your plugins
6. Your log is missing the actual crash, that's most likely and ArrayIndexOutOfBoundsException: -1, but with the points above it could be anything...

 

Locked. You seem to have found the wrong forum. This isn't our software.

For best results, always stick with the server you know and trust: CraftBukkit.
