Description:
------------
The gearman-developers ppa recently updated gearman to 0.32 which forced us to rebuild pecl/gearman (1.0.2 at the time of this ticket).

Everything builds fine and tasks run but once the task completes the php process exits with the following warning:

PHP Warning:  GearmanWorker::work(): flush(Broken pipe) lost connection to server during send -> libgearman/connection.cc:753 in /xxx/forkTask.class.php on line 60

Line 60 is a while($worker->work()) {} statement.

The first task completes, but then subsequent tasks are not "picked up" since the php process running this handler is killed.


Expected result:
----------------
No output, just continue the while loop and pick up the next worker

Actual result:
--------------
PHP Warning:  GearmanWorker::work(): flush(Broken pipe) lost connection to server during send -> libgearman/connection.cc:753 in /xxx/forkTask.class.php on line 60

php process exits

I setup a simple worker that does nothing and a client that sends 5 tasks to the 
worker. I cannot reproduce. Can you please provide a simple worker script that 
causes this?

I too have this problem.  Code is below.  Note that gearmand is being run on a remote server on the internet that is 12 hops away (31ms ping time).  Appropriate firewall ports are open (otherwise the initial connection would fail, of course).  PECL package gearman, version 1.0.2 stable.  The d() function just echoes a timestamped string to the console.

$gw = new GearmanWorker();
$gw->addServer("myserver.on.the.internet.com", 4730);
$gw->addFunction("myfunc", "myfunc_fn");

while($gw->work()) {
	if ($gw->returnCode() != GEARMAN_SUCCESS) {
		d("Return code: ".$gw->returnCode());
	}
}
