我刚刚在我的网站上设置了 nginx，当访问者访问 php-cgi.exe 并且网站变得非常缓慢时，我不确定它是否正在加载。从我所见，nginx.exe 仍然作为服务运行。下面是我的错误日志（每次都是相同类型的消息），我认为它们与 ajax 调用有关，我对它为什么这样做以及如何修复它感到非常困惑。

停止和启动 nginx 再修复 5 分钟，直到进行大约 15 次 ajax 调用，直到它再次崩溃！！？每 1 秒调用一次 ajax 调用来更新聊天框
阿贾克斯：
function loadMessages()
{
$.ajax({
type: "GET",
url: '<?php echo $config['website']['url']; ?>/assets/hk/ajax/staff_messages.php',
success: function(data) {
if (staffContent != data)
{
var div = document.getElementById('staffmessagesArea');
div.innerHTML = data;
staffContent = data;
updateScroll();
}
}
});
setTimeout(loadMessages,1000);
}
