So whenever 1 person log on to my sever the server window keeps spamming the overwhelmed message and while it only kinda effects the server I would like to get fix this. I am using a somewhat old desktop that has 1 gb of ram (ddr 2?) and is only used for the server and nothing else. Any help would be greatly appreciated.
You can try my post linked in my sig. You'll want to be running a version of Linux to get the most out of that hardware.
Yeh, not enough info. Although I can tell you that 1 gig of RAM is not much to host a CraftBukkit server.
I'll assume three things. Your using VISTA, Your CPU is bad and you have 1 gig of ram. Essentially you probably have about 300 MB of ram to use towards the server after all said and done. Get a better computer or upgrade.
