title: Zabbix server is not running: the information displayed may not be current
body: <p>So all of a sudden, after a week of using it, I get an error message on my <code>zabbix server</code> gui (<a href="http://localhost/zabbix/" rel="noreferrer">http://localhost/zabbix/</a>.) </p>
  
  <p>The error says: <code>Zabbix server is not running: the information displayed may not be current.</code> </p>
  
  <p>Any idea why is this happening ll of a sudden and out of the blue? I restarted the machine - which should automatically restore the <code>zabbix server</code> upon startup - but it's still not running. </p>
  
  <p>I also researched for a startup or restart command but true to form with <code>zabbix</code> helpful, clear documentation is non-existent. </p>
  
  <p>EDIT: </p>
  
  <p>Some more info: </p>
  
  <p><code>MySQL</code> is running normally. I'm able to <code>select</code>, <code>insert into</code>, whatever I want. </p>
  
  <p>Doing <code>/etc/init.d/zabbix-server status</code> results in  <code>* zabbix_server is not running</code></p>
  
  <p>The last entry in <code>zabbix_server.log</code> is <code>Zabbix Server stopped. Zabbix 2.2.9 (revision 52686).</code></p>
  
  <p>Doing <code>sudo /etc/init.d/zabbix-server start</code> results in  <code>* Starting Zabbix server zabbix_server</code> but the status is still <code>not running</code> and the log file doesn't have any new entries. </p>
