>Description:
The platform is: 
FreeBSD 7.2-STABLE #0: Thu Oct 15 07:23:17 CEST 2009
PHP 5.2.11 with Suhosin-Patch 0.9.7 (cli) (built: Oct 15 2009 22:16:22)
apache-2.2.13


- Problem not tied to a specific version of OS or PHP
- Vanilla installation of Horde http://www.horde.org
- Identical problem present on two servers
- Problem started to occur spring 2009
- Low server load
- Intermittent
- Comes and goes at certain times during the day. Usually, the problem will start around 11:30 CEST or 10:30 CET, last for 24h and then go away for another 24h.
	And yes, we have looked for causes for this behaviour
- Happens regardless of cache configuration in Horde, even without any caching
- Happens regardless of cache and session settings in php.ini
- The below is an *example*
- One more user on the Horde lists have reported same problem with same OS (FreeBSD)

>How-To-Repeat:
Install Horde/PHP5/Apache from ports and wait.

*example* of where this occurs:

    function factory($driver, $params = array())
    {
        if (is_array($driver)) {
            $app = $driver[0];
            $driver = $driver[1];
        }
        $driver = basename($driver);
        if (empty($driver) || $driver == 'none') {
            return new Horde_Cache($params);
        }
        if (!empty($app)) {
            include_once $app . '/lib/Cache/' . $driver . '.php';
        } elseif (file_exists(dirname(__FILE__) . '/Cache/' . $driver . '.php')) {
            include_once dirname(__FILE__) . '/Cache/' . $driver . '.php';
        } else {
            include_once 'Horde/Cache/' . $driver . '.php';
        }
        $class = 'Horde_Cache_' . $driver;
        if (class_exists($class)) {
            $cache = new $class($params);
        } else {
            $cache = PEAR::raiseError('Class definition of ' . $class . ' not found.');
        }
        return $cache;
