i donot know how the system or perl is giving the error.

can you please provide some more details on it.

i had read somewhere that perl should be compiled with the "usemymalloc=y" compiler flag to release the memory.

when i ran the perl -V on the commandline i could see this flag set to "y".

Also the only contributing factor to increase in the process memory , seems to be because of hash.

please see below the memory increase in the process ,it remain constant to some point , and then gaian start increasing :
