Description Jason Smith 2004-12-15 10:26:12 EST

User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.4.3)

Description of problem:
There is a known memory leak in the version of perl's XML::Parser
module that is shipped with RHEL3, see the changelog for the current


I can verify that this memory leak is real.  I have a long script that
I am running as a daemon which uses the XML::Parser module.  After
only a few days of running it doubles in memory, so I was forced to
use a cronjob to constantly restart it.  Then I checked if there was a
newer version on CPAN and replaced the RHEL3 version with the latest
version I downloaded there.  The current version from CPAN completely
eliminated my memory leak problem.

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1. Long running daemon script that is constantly parsing xml data.

Actual Results:  The perl process memory footprint doubles after
several days.

Expected Results:  The memory footprint should stabilize after some time.

Additional info:

This is a known memory leak that was fixed over a year ago in CPAN.
