Out of RAM after 30 seconds of a reboot?!

Hey guys,
Last night my server crashed after getting this message:

Code:

java.lang.OutOfMemoryError: Java heap space

I rebooted my server, then I lauched my server again. It had the same message as soon as the worlds loaded.

Does that message appear when a lack of RAM occurs? Any help on how to fix this would be great!

-Tom

Additional info:
My PC has 4GB of RAM

 

maybe the java process was still trying to unallocate RAM while you rebooted it? does the message still happen when you launch it now?

 

Yup.

 

you seem to hit the weirdest problems.

 

It's always me! xD

 

Just for additional information, I have tried to help him by getting him to use

Code:

java -Xms2G -Xmx2G minecraft_server.jar

instead of the default. He is also using 64 bit Java

 

Can we see your startup log? Server.log

 

Stop server > Clear Cache > Start Server?

Since this error there has been a lot of plugins which appear outdated. This did not happen before the error.

 

Tomrocks99 remove multiverse and logblock and restart (you can put them back later). Does it work then?

 

i see a few outdated plugins, but not enough to cause much :S

 

Blake305 Yes! Thanks . Do you know which plugin caused this, or was it both?

 

Probably Multiverse... How many worlds do you have loaded?

 

Ah, It was multiverse. I have got the new beta one and it works fine now. Thanks Blake305 and necrodoom for your help.
