Solved Server crashing.

My server is crashing, on average it will happen after about half an hour of being up, but sometimes it won't stay online for as little as 5 minutes and it will not come back up, instead it spams the log with '[INFO] Read timed out' occasionally until I restart the server.

There are no errors at all in my log on start-up, or when I reload my server, so I've no idea what is causing the problem.

I'm looking anywhere I can for a resolution as this is a pretty major issue, and I operate a rather large server. Any assistance would be greatly appreciated, and if you require any further information to help me fix this problem, I'll be more than happy to provide; also I've provided these if they help:

Thanks in advance.

 

Use VoidChunk to fix the broken files. (the chunks affected MAY be deleted, better make a backup)

 

Thanks for the suggestion, but can you explain how to install this mod? I've tried to use similar world repair tools before, but I'm not exactly sure how to install them to my server, to fix the world files.
Also when I get it to work what should I search for?

 

Have you tried to make a new map and find out if its the map?

 

No, but I'll add a white-list to my server, backup the map then just leave it on for a while, before I use VoidChunk, to find out if the world is in fact causing the crashes s before I use it, (Although I'm pretty positive it is).

However sometimes it can take quite a few hours before it will go down so it'll probably a while from now to find out.

 

It can also be a outdated plugin for an example my minecraft server crashed every fifth minute because of mccarpet plugin were outdated

 

Yeah, I've heard this before. I'm going to update all of my plugins to their latest versions tomorrow. Thanks for the suggestion.

 

And also remember to delete inactive plugins

 

So I deleted all the worlds on my server, and left it on for 12 hours and it didn't crash at all. So this probably means that the crashing bug is something to do with the map. However, to not cause confusion among players I white-listed the server for this period of time, so the crashing could also be caused by something to do with the players like crashing when a certain command is used (eg. /tp)

 

I can say it's chunk error not overused commands that causes the crash..... (ChunkRegionLoader.java:80)

 

People being in a region (=> chunk) due to commands (/tp)

 

So do you know

It's a tool that fixes your map by itself, it's not like MCEdit tho.

 

Well I decided to just reset my world to a new world, as I needed to get the server online soon. But can you explain how to install VoidChunk, in case it happens again. Would I just have to put the .jar file in the /plugins folder and the .bat in the server folder? Or would I put it in the world folder? I don't understand, and the plugin description isn't very clear on installation.

 

It's neither a plugin nor a mod, just an application written in Java
Actually you'll put the .jar and .bat in your bukkit folder (beside the craftbukkit.jar and server.properties, etc.) and double click the .bat. Then you'll see a console window with some more help text

 

Will keep that in mind, thanks for your help.
