mod_perl2 memory problem

Hi all,
I have compiled apache webserver with this configuration:

./configure --prefix=/foo/apache-2.2.23-worker-1st --enable-modules=all
--enable-mods-shared=all --disable-ipv6 --enable-ssl
--with-ssl=/foo/openssl-1.0.1c --enable-proxy --enable-proxy-connect
--enable-proxy-http --with-mpm=worker --enable-cgi

without mod_perl without mod_perl each httpd process take 12m

with mod_perl  each httpd process takes 38m

and each request the memory increase the memory.

mod_perl version is 2.0.5.

Thanks
idel
