in thread out of memory problem after undef

Hey All, I too ran into more or less the same issue as did Tim, so does anybody have an answer for suggesting perl to defragment its memory pool ? Its really bad and frustrating coz despite having a memory of 2GB eaten up by Perl it is not able to meet the need of storing 200MB of data. Big Monks - Please help me out....

    Perl it is not able to meet the need of storing 200MB of data.

    Here is a 200MB file:

    C:\>dir acktrace 14/06/2012 18:51 206,937,739 acktrace

    And here is a perl script loading 10 copies of that file into less than 2GB of memory; then discarding it and recovering all the memory:

    c:>perl -E"undef($/); $f[0]=<>; $f[$_]=$f[$_-1] for 1..9; say`tasklist +`; undef @f; say`tasklist`;" acktrace | find "perl" perl.exe 7996 Console 1 1,927 +,000 K perl.exe 7996 Console 1 4 +,796 K

    Don't blame Perl, or ActiveState or Windows because you don't know how to use them effectively.

    If you want actual help; post the actual code.

    The start of some sanity?
