If you supply more than one server, it will always take the last server, unless it is unavailable. This is the way gearman works (and it is generally not a bad idea).

If you want to spread the jobs over multiple servers, you might want to shuffle the list of servers.

actually client side will throw an exception when any of the servers is down or unreachable instead like

Fatal error: Uncaught exception 'GearmanException' with message 'Failed to set exception option' in /var/www/ipao/Api/Q2/Test/gm-test.php:11
