Any ideas how can I fix it?

 

There is no fix as of yet, this happens on all server. It really isnt a problem you need to worry about.

 

This happens to people running off their computer..
If they are running other applications or their computer gets a burst of ram usage somewere else
So your server will not use as much ram and start lagging and that message will display
Nothing to worry about really just laggs you slightly

 

Well I'm using virtual server

 

We have the same problem with our server and we have a quad core 3.2 ghz with 24gb ram and get read time out errors like every 10 min. We run te same plugins as above and we want to know why te server crashes is it bukkit or is it java that couses this problem?

 

I have the same issue. It says: "Can't keep up! Did the system time change, or is the server overloaded?" I want to know how to fix this. I run both my server and minecraft at the same time on the same computer. Please Help.

 

How much RAM do you have?
