从命令行运行Gearman PHP的分段错误

我使用Ubuntu Natty与PHP 5.3.5和PECL Gearman 0.8.0。以下是版本信息:

PHP 5.3.5-1ubuntu7.3 with Suhosin-Patch (cli) (built: Oct 13 2011 22:20:48)

当我试图通过命令行运行Gearman客户端(我已经有我的工人运行)时，我得到一个分段错误。

下面是我在命令行上得到的结果:

root@Local:~/sandbox# php php_gearman_client.php
Sending job
Segmentation fault

下面是我的工作代码:

<?php
echo "Starting'n";
# Create our worker object.
$gmworker= new GearmanWorker();
# Add default server (localhost).
$gmworker->addServer();
# Register function "reverse" with the server. Change the worker function to
# "reverse_fn_fast" for a faster worker with no output.
$gmworker->addFunction("reverse", "reverse_fn");
print "Waiting for job...'n";
while($gmworker->work())
{
  if ($gmworker->returnCode() != GEARMAN_SUCCESS)
  {
    echo "return_code: " . $gmworker->returnCode() . "'n";
    break;
  }
}
function reverse_fn($job)
{
  echo "Received job: " . $job->handle() . "'n";
  $workload = $job->workload();
  $workload_size = $job->workloadSize();
  echo "Workload: $workload ($workload_size)'n";
  # This status loop is not needed, just showing how it works
  for ($x= 0; $x < $workload_size; $x++)
  {
    echo "Sending status: " . ($x + 1) . "/$workload_size complete'n";
    $job->sendStatus($x, $workload_size);
    sleep(1);
  }
  $result= strrev($workload);
  echo "Result: $result'n";
  # Return what we want to send back to the client.
  return $result;
}
# A much simpler and less verbose version of the above function would be:
function reverse_fn_fast($job)
{
  return strrev($job->workload());
}
?>

<?php
# Create our client object.
$gmclient= new GearmanClient();
# Add default server (localhost).
$gmclient->addServer();
echo "Sending job'n";
# Send reverse job
do
{
  $result = $gmclient->do("reverse", "Hello!");
  # Check for various return packets and errors.
  switch($gmclient->returnCode())
  {
    case GEARMAN_WORK_DATA:
      echo "Data: $result'n";
      break;
    case GEARMAN_WORK_STATUS:
      list($numerator, $denominator)= $gmclient->doStatus();
      echo "Status: $numerator/$denominator complete'n";
      break;
    case GEARMAN_WORK_FAIL:
      echo "Failed'n";
      exit;
    case GEARMAN_SUCCESS:
      break;
    default:
      echo "RET: " . $gmclient->returnCode() . "'n";
      exit;
  }
}
while($gmclient->returnCode() != GEARMAN_SUCCESS);
?>

编辑

显示分割错误是由Imagick引起的。所以我做了以下的事情来处理这个问题。

1. 删除图像dpkg --purge --force-all php5-imagick。我在设置PHP
时安装了这个
2. 重新启动PHP(这可能取决于你如何安装PHP)
3. 重启Gearman Job Server /etc/init.d/gearman-job-server stop && /etc/init.d/gearman-job-server

一切似乎都正常了。
