Server won't stay online longer than 5mins.

My server is crashing constantly, usually won't stay up for longer than 5-10mins, and it does not come back up, instead it spams the log with '[INFO] Read timed out' until I restart the server.

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.

If you require any further information to help me fix this problem, I'll be more than happy to provide. However to try and fix this I've updated all of my plugins to their latest versions, and I'm using the latest beta build of Bukkit, but still nothing.

Also, a full crash report of my usual error can be found here: http://pastebin.com/diHAxPpd

 

First of all make sure you computer is not falling asleep

Second try giving your sever more RAM

Third limit what other activities are running on your computer or try reducing plugins

Lastly if nothing else works

Fourth demote down to the last recommended build until a recommended build comes out for the current version
