Please answer these questions before submitting your issue.

1. What did you do? If possible, provide a simple script for reproducing the error.
   $http = new \Swoole\Http\Server('0.0.0.0', $port);
   $http->on("start", function (\Swoole\Server $server) {
   echo 'success'.PHP_EOL;
   });
   $http->on('request', $grpc->handler());

    $http->set([
        'enable_coroutine' => true,
        'worker_num' => 3,
        'open_http2_protocol' => true,
        //'log_file' => '/var/log/swoole.log',
        //'daemonize' => true
    ]);
   
    swoole_set_process_name("grpc_server_".$strClasses);
    $http->start();
   

2. What did you expect to see?

要怎么调整才能 正常返回json串

3. What did you see instead?

想返回一个60多kb的json，但出现了
WARNING check_worker_exit_status: worker#2[pid=104] abnormal exit, status=0, signal=11

升级一下版本，使用 4.8 或者 5.1 ，建议使用 valgrind 跟踪程序运行。
