Answer 1

The memory settings for eclipse is in eclipse.ini. Increase your setting from -Xmx1000m to i.e. -Xmx2000m.

Answer 2

I don't think this has anything to do with memory. What eclipse version are you using? It sounds like a bug on previous Eclipse version: https://bugs.eclipse.org/bugs/show_bug.cgi?id=324491

Answer 3

Try http://java.sun.com/docs/hotspot/gc1.4.2/#4.2.2.%20AggressiveHeap|outline

The option -XX:+AggressiveHeap lets the vm allocate dynamically more memory.
