After a few hours of running my server, the server starts to lag. To fix it, I turn it off for 5-20 minutes. After that, the lag would be fixed, but it would come right back in 5-10 minutes. I play on the laptop the server is hosted on and it is a hamachi server. I have a 32 bit Window XP laptop (Version 2002; SP 3). My craftbukkit build is "1.2.5-R1.0". It also spams [WARNING] Can't keep up, did the system time change or is the server overloaded? I play with about 2-8 people at a time on my server and this is my run.bat info: Code: @ECHO OFF SET BINDIR=%~dp0 CD /D "%BINDIR%" "%ProgramFiles%\Java\jre6\bin\java.exe" -Xmx1375M -Xms1375M -jar craftbukkit.jar PAUSE The plugins I use are: lockette mcMMO BKCommonLib Essentials EssentialsSpawn Lockette Timber So is there any way to fix this?
