Every Embperl release is tested for memory leaks before I release it. Also
1.3b3 and 1.3b4 surely has _no_ memory leaks.
Embperl caches the precompiled Perl code of your scripts. If you have many
scripts 12-15 MB isn't unusual. The size should settle once you have
requested every script once. Currently there is no possibility to limit the
httpd size i.e. no possibility to throw precompiled perl code out of memory,
but you may read the mod_perl_tuning.pod that comes with mod_perl (or the
mod_perl guide on the website) for tuning the size of your httpd.
If the size of your httpd increases also you don't request any new scripts,
then there is either a memory leak in one of your scripts itself or in one
of the modules you are using.
