   causing timeouts:

 * You should increase the memory limit for PHP scripts. Something consumes all 
   available for PHP memory, so Cerber is unable to proceed and complete its operations.
   Also, Cerber is unable to connect to the database, probably you use an alternative
   incompatible DB driver/plugin, etc.
