title: session.save_path incorrect in magento + memcache for session
body: <p>I am trying to configure Magento to use memcache for session. I have installed memcached and also php5-memcache. I have also added "extension=memcache.so" in memcache.ini.</p>
  
  <p>I have made sure the memcached instance is also running in the localhost port number 11213. However, when I try to login to Magento admin I get an error -</p>
  
  <pre><code>Warning: Unknown: Failed to write session data (memcache). Please verify that the current setting of session.save_path is correct (tcp://127.0.0.1:11213?persistent=0&amp;weight=2&amp;timeout=10&amp;retry_interval=10)  in Unknown on line 0
  </code></pre>
  
  <p>The following is the memcache configuration in local.xml -</p>
  
  <pre><code>&lt;session_save&gt;&lt;![CDATA[memcache]]&gt;&lt;/session_save&gt;
  &lt;session_save_path&gt;&lt;![CDATA[tcp://127.0.0.1:11213?persistent=0&amp;weight=2&amp;timeout=10&amp;retry_interval=10]]&gt;&lt;/session_save_path&gt;
  </code></pre>
  
  <p>The following are the grep for memcached,</p>
  
  <pre><code>www-data    1329     1  0 08:13 ?        00:00:00 /usr/bin/memcached -d -m 64 -p 11213 -u www-data -l 127.0.0.1
  www-data  1511     1  0 08:18 ?        00:00:00 /usr/bin/memcached -d -m 64 -p 11211 -u www-data -l 127.0.0.1
  www-data  1518     1  0 08:18 ?        00:00:00 /usr/bin/memcached -d -m 64 -p 11212 -u www-data -l 127.0.0.1
  </code></pre>
  
  <p>I have been meddling up with this for a couple of days now and I am not sure what the issue. Any help is appreciated.</p>
  
  <p>Thanks,
