1. What did you do? If possible, provide a simple script for reproducing the error.

$workerNum = 2;//线程数

$pool      = new Swoole\Process\Pool($workerNum);

$pool->on("WorkerStart", function ($pool, $workerId) use ($database, $params, $logger,$workerNum) {
    try {
    $mysqli = new Mysqli($database['host'], $database['username'], $database['password'], $database['dbname']);
    $table  = 'excel_task';
    $rest_service = new ResetService();
    while (true) {

            //利用swoole线程池
            $sql = "
                select user_id,
                   executable_path,
                   action_name,
                   args_json,
                   id
              from `excel_task`
             where flag= 0
               and action_name is not null
               and mod(id,$workerNum)=$workerId
               and `executable_path` IS NULL 
             ORDER BY `id` asc;
                ";
            $result = $mysqli->query($sql);
            $res    = $result->fetch_row();

            if ($res) {
                $v           = $res;
                $process     = $pool->getProcess();
                $executable  = $v[1] ?? $params['config']['application']['appDir'] . 'cli.php';
                $action      = explode(',', $v[2]);
                $task_name   = $action[0];
                $action_name = $action[1];

                $arg2        = $v[4];
                if (empty($action_name)){
                    $args = [$executable, $task_name, $arg1,$arg2];
                    $process->exec(PHP_BINDIR . '/php', $args); // exec 系统调用
                }else{
                    $args = [$executable, $task_name, $action_name, $arg1,$arg2];
                    $process->exec(PHP_BINDIR . '/php', $args); // exec 系统调用
                    

                }

            } else {
                sleep(1);

            }

    }
    } catch (\Exception $e) {
        $logger->write_log("=================begin hubbonusAction " . time() . "==========", 'info');
        exit;
    }
});
$pool->start();
$logger->write_log("=================begin hubbonusAction " . time() . "==========", 'info');

3. What did you expect to see?
   $process->exec() 正常调起新进程

4. What did you see instead?
   PHP Warning:
   Swoole Process::exec(): execv(/usr/bin/php) failed, Error: Argument list too long[7]

命令参数无法传递太长的内容，建议使用标准输入输出与进程交互，而不是将所有内容都放到 argv 中。

您说的这个怎么实现呢？能举个简单的例子吗？
