Bug #12558: pgsql connections apparently not being closed

From: zeekamotay@hotmail.com Operating system: linux PHP version: 4.0.5 PHP Bug Type: PostgreSQL related Bug description: pgsql connections apparently not being closed web server: RedHat 7.0, kernel 2.2, Apache 1.3.20, PHP 4.0.5 db server: RedHat 6.2, kernel 2.2, Postgres 7.1.2 configure: ./configure \ --with-apxs=/usr/local/apache/bin/apxs \ --with-config-file-path=/usr/local/apache/conf \ --disable-xml \ --disable-pear \ --enable-magic-quotes \ --with-curl \ --with-imap \ --without-mysql \ --with-pgsql=/usr/local/pgsql \ --enable-trans-sid \ --with-regex=php \ --enable-memory-limit \ problem: PHP is apparently not always closing connections to the database server. At any time, the number of Postgres processes running on the database server will be 20-100% more than the number of httpd processes running on the web server. Eventually, the database server will hit its maximum number of concurrent connections allowed, and deny further access, even though 90+% of the running Postgres processes are idle. This problem exists whether or not I use persistent connections. Turning off Apache keepalives seems to make the problem much less dramatic (i.e., it takes a lot longer to eventually hit the max connections), but it doesn't cure it. This problem occurs with PHP 4.0.4pl1 and 4.0.6, and Postgres 7.0.3, as well. Don't know where to turn next... any ideas? Thanks. -- Edit bug report at: http://bugs.php.net/?id=12558&edit=1
