Large size object - writing problems....

Dear all,

    I am trying to write in a file an object which has a considerably large size, ~450 MB (value extrapolated from simpler cases). While creating and filling the object, everything is fine, while trying to write it in the file, checking with top, the size in memory increases too much (much more than simply summing the memory required to run the program - AliRoot - and the memory the object would need), and then the process crashes with segmentation violation. Does someone know how to overcome this problem? Is there any particular "flag" I should set to write large objects?

    Thank you a lot for your help.
    Cheers,
