Doctrine Second Level Cache not doing anything
<p>I have a bunch of entities and would like to test the Second Level Cache but I can't get it to work. I just get zero hits, misses &amp; puts in the profiler.</p>

<p>All entities have annotations as below.</p>

<pre><code>use Doctrine\ORM\Mapping AS ORM;

/**
 * @ORM\Entity
 * @ORM\Cache(usage="NONSTRICT_READ_WRITE", region="my_region")
 */
class Property extends Base\PropertyBase
{
</code></pre>

<p>My config file has -</p>

<pre><code>doctrine:
    orm:
        metadata_cache_driver:
                type:           memcache
        result_cache_driver:
                type:           memcache
        query_cache_driver:
                type:           memcache
        second_level_cache:
            region_cache_driver:
                type:           memcache
            enabled:              true
            log_enabled:          true
            regions:
                my_region:
                    cache_driver:  memcache
                    lifetime:   3600
</code></pre>

<p>The profiler shows the cache is enabled but I am not getting any activity.</p>

<p>Any suggestions as to how I might debug this?</p>
