It happens if you got only a little amount of RAM (< 2GB) and you use a datfile which got roms listed which are rather big (like > 1GB). The cause of this is the auto-memory option of the rebuilder, which tries to allocate the biggest current rom-size as ram for the no-recompress functionality.

Turn off the 'auto' option for "memory used for 'no recompress'" in Rebuilder advanced for the given profile. If you can't open it, set "Rebuilder_AutoMemory = off" in the belonging settins/*.cmp file.

I think I should limit the maximum value to 1/2 of the system's ram in the next version.
