I believe that this is actually a problem of the package rrdtool since librrds-perl just wraps the C library.
The problem seems to be fixed upstream: http://oss.oetiker.ch/rrdtool-trac/changeset/2117 I just tested the latest stable release 1.4.5 from http://oss.oetiker.ch/rrdtool/pub/ and the memory leak no longer occurs.
