Adding to Amit's comments, I found that if the first server in the list of servers is down, then there seems to be no way to handle such a condition.

The addServer and addServers are unforgiving when any of the addresses are down. I tried using exceptions, but it does not quite work. Can you provide a working example to handle a list of servers where one or more is not running.
Thanks

Since a few versions the port parameter is not optional anymore. I have version 1.1.1 of pecl/gearman compiled with libgearman 1.1.5, and I'm getting the following error:
send_packet(GEARMAN_COULD_NOT_CONNECT) Failed to send server-options packet -> libgearman/connection.cc:430
This happens if you don't provide a port.
Just set the second parameter to 4730 and it is working again.
