我正在尝试将数据从CSV转储到数据库中。这很费时间，所以我决定使用laravel队列。
服务器和本地主机之间的主要怪异之处是：
$insertJob = (new StoreUser($data))->delay(Carbon::now()->addSeconds(3));
dispatch($insertJob);
$msg = [
'status' => '1'
];
echo json_encode($msg);
exit();
在上述情况下，在分派作业后，它将在本地主机中发送status - 1。因此，它弹出一条消息“作业完成后，您将收到电子邮件通知”。但是，在服务器中，它会继续显示上传栏，即不会回传状态。
一段时间后，它显示服务器内部错误。
PHP错误日志：
27351#27351: *114475 FastCGI sent in stderr: “PHP message: PHP Fatal error: Allowed memory size of 1073741824 bytes exhausted (tried to allocate 20480....)
即使在本地主机上我也没有得到它，我正在分配128MB，而在服务器上大约是1GB。

我一无所知，可能是什么原因。让我知道您是否需要其他信息。
更新：
production.ERROR: Allowed memory size of 2147483648 bytes exhausted (tried to allocate 20480 bytes)我非常确定更新分配内存不是解决方案。因为我在128MB的本地服务器上成功处理了该问题，即使在2GB的服务器上也无法解决此问题
答案 0 :(得分：1)
经过大量搜索，我发现这是由于.env文件中的一个简单差异所致。
我需要更新
QUEUE_DRIVER=sync
到
QUEUE_DRIVER=database
在服务器中。
