我正在寻找有关为什么大于 128K 的邮件请求因返回的 500 或 404 而死亡的线索。
php脚本包含与此部分类似的内容
$arContext['http']['timeout'] = 60;
$context = stream_context_create($arContext);
$FileContents = file_get_contents('php://input', 0, $context);
syslog(LOG_INFO, "File length = " . strlen($FileContents);
服务器端：
post_max_size = 8M
memory_limit = 32M
syslog显示这些失败帖子的文件长度为131702。
此时，这似乎只是卫星连接的问题，但不确定如何解决这个问题。
来自服务器端的Wireshark包括：
