I have removed all the extra, I was just trying to see if it helped. I am currently on OSX and the java app rarely goes over 1.5gigs. The thing is I've never gotten this message before today. I've always gotten lag spikes but the server has never been overloaded. I don't mind the error, as I do get it sometimes after my computer sleeps and such and the server is fine. But the 20 second lag when placing blocks is unbearable.
