The development PC i use is a single CPU , 2GB ram , winXP, machine... and the target machine on which i test the script is a standalong workstation machine with 4 x86_64 cpus and perhaps 2gb+ ram ...and Suse linux and i also tested the same on a virtual machine with RedHat Linux, with 512 mb ram...
anyways with the presizing of hash the problem is solved ...
