Mine Craft Server Error - Page 2

post #11 of 22
This message usually pertains to hard drive speed issues, not RAM. It's a blanket error saying there is a bottleneck somewhere. You can host your world on a seperate HDD (atleast 7200RPM or above) but my 7200RPM barracuda still causes this error. You can get a SSD or a 10-15k HDD that might help, or a lot of people like to use RAMDISK to host their worlds for the fastest performance possible.

There is a bukkit plugin(obushutthehellup) that hides this from spamming your console but for the msot part this is a common error that happens all the time in prolly 50%+ of the servers out there I bet.

I checked, and it's probably indeed the harddisk. I'd say it especially happens when your players move quite far away from eachother, causing the server to load more map chunks, and perhaps even have to generate them.

Even an older 36 GB 10.000 RPM disk couldn't keep up. Will try again with a SAN array

I've read of people still getting this error with SSDs. YOu can use a plugin like performance tweaks to help keep more chunks loaded at a time in addition to changing it from saving every second to a configurable time period but I had problems with this plugin not auto saving properly

Now I'm getting a new error as follows:

[INFO] Starting minecraft server version Beta 1.6.6

I tested my new RAM by replacing it with my old RAM I just upgraded and got the same problem. So I can rule out my new RAM sticks. Plus I've checked two utility places where it's reading all 12GB now.

Any reasons why I'm running out of memory?

Ok one thing I've just noticed is when I created the .bat file as the video I posted it didn't allow me to open it to run.

As quickly as it wanted to open it closed. Any reason for this?

I can't open the .bat file. As soon as it opens, it closes before I can even read a word. I ended up reinstalling minecraft in same file folder and somehow it's working now. At least temporarily.

Still getting the WARNING] **** NOT ENOUGH RAM!
[WARNING] To start the server with more ram, launch it as "java -Xmx1024M -Xms1024M -jar minecraft_server.jar" error at start up.

kids going to play it today while I'm at work. Will let you know tonight if re-installing it worked.

it sounds like you need to read some tutorials

the default start bat only runs 512mb or ram I believe, it won't recognize your max amount of ram

you need to right click on the .bat and edit it with note pad. you need to edit the max amount of ram and everything in the .bat via notepad or notepad++

open it in notepad and post the contents here

while you are at it download the 64 bit version of Internet Explorer and open it up and go download and install the 64 bit version of java

A solution : Use Windows 64, use java 64 ( to allocate more than 1.5 Gb ) and start java with more RAM -

Best solution : Install VirtualBox, install MineOS+ and start the VM with a lot of RAM. Use the RAMDISK install option for MineOS+ : you now have the fastest harddrive ever.

Ok, in order to fix this issue I was having I had to do two things.

One, I down loaded 64bit java like recommended.

Two, that didn't allow me to log in still so I had to restart a fresh new download of Minecraft and I was able to set up a Minecraft.bat file, where I applied the line that The Punisher advised me "C:/Program Files/java/jre6/bin/javaw" -jar -Xmx10G minecraft_server.jar", only I used 6GB as my file size.

I was able to open and start the Minecraft server from the Minecraft.bat file now where I no longer see the "To start the server with more ram, launch it as a 'Java Xmx1024M - jar minecraft_server.jar" error.

I now hope that my kids & newphews who are starting a new world don't run into any problem with size limitation. They were sad that all their hard work was deleted and they had to start over. I'm hoping that 6GB size will be substantial and they won't hit a wall again where I can't log in.

Thank you for those who helped and I hope that this thread might come in handy for someone else like me who's never set up a server and a n00b.

+1 rep went to The Punisher and The D0ctor

I'd advise to keep some memory for the OS. Don't allocate your full amount of memory to Minecraft. My Debian server keeps 128 megs for itself, and allocates the rest to Java.

It's strange that you weren't able to keep your world though? can't you copy the world folder, and edit server.properties to use that world?
