pear::HTTP_Request and pear::Net_Socket

Hi, I'm using pear::HTTP_Request and I'm having difficulty gaining memory that already used by pear::Net_Socket. I got the following error after running my script <b>Fatal error</b>: Allowed memory size of 8388608 bytes exhausted (tried to allocate 4097 bytes) in <b>/usr/share/pear/Net/Socket.php</b> on line <b>243</b><br /> Allowed memory size of 8388608 bytes exhausted (tried to allocate 0 bytes) Is it possible to free up memory that already used by pear::Net_Socket? I've tried checking on how many memory it consumed and i found out that after doing a 20,000 pear::HTTP_Request loop, it eats almost 8MB of RAM on 50% or 10,000 pear::HTTP_Request loop only and the script stop. AFAIK increasing 8MB memory limit is not advisable. Any idea or workaround on this? TIA
