I am currently working on a project which requires reading up 30 Million records from MS SQL by calling a stored proc and process. The following script works for smaller runs, but die without any error/warnings from Perl at about 2.5 Million.

The stored proc has been tested from MS SQL client and it finishes successfully (it takes like 6 hours). I am just wandering if there is something wrong from the following code or is there any parameters in DBI that I should set to make Perl wait for the whole set of records indefinately? 

    my $cdr_list = {};

    eval
    {
        my $query = "EXEC prc_getUsage $run_id, 'CDR', '$start_account
+', '$end_account'";
        print "\t\tpreparing query [$query]\n";
        my $sth = $utils->{DBH}->prepare($query);
        print "\t\texecuting query\n";
        $sth->execute();

        my $i =1;
        print "\t\tfetching records\n";
        while (my $record = $sth->fetchrow_hashref())
        {
            my $msisdn = $record->{MSISDN};
            #print "\t\tfetchrow [$msisdn] [$i]\n";
            $i++;
            unless (defined $cdr_list->{$msisdn})
            {
                $cdr_list->{$msisdn} = [];
            }

            push @{$cdr_list->{$msisdn}}, $record;
        }
        $sth->finish();
    };
    print "\t\tCompleted selecting CDRs\n";
    if ($@)
    {
        # Try to check for connection error
        if ($@ =~ /(SQL\-28000)|(SQL\-08S01)/)
        {
            $utils->log_error("$@\n", $MAXIS_ERROR_DB_CONNECT);
            $utils->reconnect();
            goto RETRY;
        }
        else
        {
            $utils->log_error("$@\n", $MAXIS_ERROR_SQL);
            print "Unhandled Exception [$@]\n";
            return undef;
        }
    }
