Shell Programming and Scripting

I have a question regarding to the following code:

Code:

foreach my $Cnt ( @Cnts ) {
  my $abc = xyx->new();
    do sth...
    aggregatedData->processData($abc);
}

my question is: whether perl will release the memory assign to "my $abc" each time after
processData($abc) is being executed.
If not,will it release the memory after for loop completes?
If still not, how to release the memory explicitly? can I put undef($abc) after
aggregatedData->processData($abc) to free the memory?

I am investigating an memory exhausting issue and I want to free memory of a variable as soon as I finish using it.

The memory pointed to by $abc will become marked as "unused" after the loop finishes. However, Perl will not immediately return that memory becauseAnd anticipating your next question: no, I do not know of any way to force Perl to release that memory.

no you cannot.
your problem is elsewhere, probably in your design.
perl is a very efficient language, I've done some massive stuff with no memory problems.
