# persistent database connections

 * I have several installs of various WP verions on a web server connecting to MySQL
   on a different host. These installs are maintaining persistent database connections.
   This is a problem as the DNS can change on the MySQL server and these installs
   keep the old.
 * The file wp-db.php _doesn’t_ have the call mysql_pconnect, but have the normal
   mysql_connect
 * We have a number of installs with the same host for both web and DB (same MySQL
   as above) and they don’t have the same issue.
 * Any suggestions on cause/solution?

 * Is that right Sam? I don’t find USE_PCONNECT in the core files…

 * it does look like it’s a relic
 * but should work if you add this to wp-db.php
 *     ```
       if (USE_PCONNECT == 'false') {
        $link = mysql_pconnect($server, $username, $password);
        } else {
        $link = mysql_connect($server, $username, $password);
        }
       ```
   
 * or maybe I’m in over my head :>)

 * I am running **zahipedia.com**
    Web site and getting this issue. site is temporally
   down
 * I called to hosting and they said all open connection has been used in the sites.
   when I checked and find the WordPress is using mysql_connect
 * should I use mysql_pconnect to avoid this issue
 * Any suggest
 * Thanks in advance
