Cedric,

Try this:

-Xms5000m -Xmx5000m

The above sets a fixed heap of 5Gb that can't be resized.
Apparently, resizing the heap is an operation that can make the JVM to
throw an OutOfMemoryException or worse.

If you drop in -Xingc (for incremental garbage collection) then
suddenly ImageJ behaves very well.
