"Freeing memory" HTTP Error log...

I'm getting this inside my httpd error log and while I haven't delved too much into what may be causing it, I'm assuming it's due to PHP4 automatically deallocating memory from a while() loop executing mysql_fetch_array($sth). I inserted a mysql_free_result() inside the PHP code and I still receive the message (note that I never looked at the error log for this before). Looking at main.c it falls inside of the following: if (message==ZMSG_MEMORY_LEAK_DETECTED) Again, not sure if this is due to the new features or not because it falls within the " if (EG(error_reporting)&E_WARNING) { " statement and may just be debugging stuff. - error_log snippet.... /home/httpd/html/saf/site/album/m_album.shtml: Freeing 0x082F0200 (1 bytes), allocated in main.c on line 935<br> /home/httpd/html/saf/site/album/m_album.shtml: Freeing 0x082ED780 (20 bytes), allocated in main.c on line 933<br> - Mike Gammon
