我在运行工作线程时出错：
Segmentation fault (core dumped)
尝试通过命令行为 Gearman 客户端运行工作线程时，我遇到分段错误。
此消息工作者在几个正确响应后得到。
我的工作代码：
<?php
require __DIR__ . '/vendor/autoload.php';
use ClickHouseDBClient;
use ClickHouseDBQuoteFormatLine;
$config = [
'host' => '',
'port' => 0,
'username' => '',
'password' => ''
];
$db = new Client($config);
$db->database('mydb');
$worker= new GearmanWorker();
$worker->addServer('127.0.0.1', '4730');
$worker->addFunction("send_to_clickhouse", "processing", $db);
while (1)
{
$worker->work();
if ($worker->returnCode() != GEARMAN_SUCCESS){
echo "return_code: " . $gmworker->returnCode() . "n";
break;
}
}
function processing($job, $db)
{
$message = $job->workload();
$data = json_decode($message, true);
$statement = $db->insert($data['table_name'], [array_values($data['columns'])], array_keys($data['columns']));
$statement->error();
echo $data['table_name']."n";
}
?>
运行辅助角色：
php worker.php
工作器输出：
table1
table2
Segmentation fault (core dumped)
我正在使用smi2/phpclickhouse扩展名将数据发送到数据库

如果我删除代码statement = $db->insert(...似乎一切正常。
知道需要做什么来解决问题吗？

我在运行PHP 7.2.24的Ubuntu 18.04 LTS中也遇到了这个问题。
我发现这是gearman-php扩展中的一个错误(已修复)。
要解决此问题，您需要下载，编译并安装齿轮工pecl模块
cd /tmp/
sudo wget https://github.com/wcgallego/pecl-gearman/archive/gearman-2.0.6.zip
unzip gearman-2.0.6.zip
cd pecl-gearman-gearman-2.0.6
sudo phpize
./configure
sudo make
sudo make install
有关 Ubuntu 上 PHP7 gearman 的完整安装，请参阅本指南
