Does not matter how much physical memory your machine has, by default 
the JVM will allocate only 4MB for heap, I think, which wouldn't be 
enough for running Marmotta. So it's important to properly configure 
those aspects, as it's described at:

http://marmotta.incubator.apache.org/installation.html#war
