memory leak?

[CapriSkye]

one of my forums user is having this memory problem. he said that whenever someone visit his gallery, his memory useage would go up and eventually crash his computer. he tried to make the gallery unaccessible by renaming the folder, then everything would be okay.
he's using php 5.02 and mysql 4.1.7, with cpg 1.3.2. his gallery is functioning properly though, just the memory problem.
this is his debug info:

anyone know what the problem is? thank you

PHP scripts do not manage memory - that is done at the level of PHP language  (Zend Engine). Firther it is unlikely that there is a true memory leak - chances are that there are some mods (like watermark on the fly) which are consuming too much memory

More details on the setup would be of help

[CapriSkye]

thanks for the reply, he's thinking maybe there are queries that aren't released in database? i'm not sure if it's cpg's problem since nobody else is having this problem, but he does say when he makes the gallery unaccessible memory won't go up.
also he doesn't have any mod installed, he does have some pictures in it, about 500 pics with around 100 users.
he's using imagemagick, with default settings i believe.

See if upgrading PHP helps. Besides, from php.net:

PHP 4.3.10 & 5.0.3 released!

[15-Dec-2004] The PHP Development Team would like to announce the immediate release of PHP 4.3.10 and PHP 5.0.3. These are maintenance releases that in addition to non-critical bug fixes address several very serious security issues. All Users of PHP are strongly encouraged to upgrade to one of these releases as soon as possible.

in PHP, you don't have to close the mySQL connection - it will close automatically. From http://www.php.net/manual/en/function.mysql-connect.php

The link to the server will be closed as soon as the execution of the script ends, unless it's closed earlier by explicitly calling mysql_close().

However, there might be an issue in relation to memory usage if you don't free the result. From http://www.php.net/manual/en/function.mysql-free-result.php

mysql_free_result() only needs to be called if you are concerned about how much memory is being used for queries that return large result sets. All associated result memory is automatically freed at the end of the script's execution.

, although I can't see where this should apply in coppermine.
