java.lang.OurOfMemoryError: Java heap space

So I made quite a few changes to my server earlier tonight, including adding 2 new worlds, getting rid of a world, and getting two more plugins. I tried to start the server, and this keeps showing up. Can someone please explain?

 

And what keeps showing up? Please post the full error.

It might be related to your new plugins, e.g. one could have a memory leak, or you might not be giving your server enough RAM.

Here's just part of it for example.

 

The 'new' world you added corrupted it. Multiverse is broken, try reinstalling & deleting the new world

 

Yeah, Multiverse currently has a bug where it will corrupt your world when you make a new one.

 

Fixed, thank you.

 

hi, I have the same Out Of Memory Java Heap Space message, and this is what it says:

Maybe update java? Sun is a Java thing I think.
This error happened to me but i just reset the server (I couldn't wait since it actually took 1 min for each plugin to disable so I forced quit) and I just ran it again then it was fine.

 

That means you ran out of memory. Allocate more memory or upgrade your server.

 

If it starts to happen suddenly for no apparent reason, it's likely an error in some code.

 

It happened after he added some worlds. More world = more memory. Therefore, he ran out of memory.

 

i have a memory problem every time i am playing it says out of memory
this is the errorlog
