I have been having trouble with both minecraft and bukkit. Last night, minecraft thought it would be cool to: Crash my computer upon log in Freeze on log in Black screen my computer Freeze windows Now that fixed, and I still don't have any idea why it did that. But that is fixed. So now, I have a new problem! Bukkit constantly throws this at me when there are 3+ people on (Before this started, I could have 10 people on, no problem.): [WARNING] Can't keep up! Did the system time change, or is the server overloaded? It will show that every 2 seconds. The server is using about 900MB of RAM out of 1.6GB. My computer specs are: AMD phenom II 955 Black edition 3.2 G.SKILL 4GB 2GBx2 Normal house internet. Plugins: AdminPrivateChat | Blaze of Glory | ChatCo | Chat Manager | Citizens | clear (Inventory clearer) | ColoredSigns | Console name | FakeOP | Falsebook | IceBanIP | iSafe | McCity Help | MineMail | Mobeggs | motd | multiworld | MyWarp | PermissionsEx | Playerstats | Plugin List | Ptweaks | Reporter | ReservedList | Super spawn | SWatchDog | TimedMessages | Time Shift | Ultra ban | Vault | VoxelSniper | WorldEdit | Worldguard I know I have a lot of plugins, but still, it just started to this. PS: I'm also using the BukkitGUI project Also, the server doesn't lag at all. It just shows the warning in the console.
