NFS共享上的“stat failed”问题

On prouction servers we have a mount point with NFS:

在prouction服务器上,我们有一个使用NFS的挂载点:

192.168.160.5:/var/www on /var/www type nfs (rw,sync,noatime,intr,soft,timeo=30,rsize=32768,wsize=32768,intr,soft,timeo=30,rsize=32768,wsize=32768,addr=192.168.160.5)

We have 2 machines that are mounted this way, but lately we are experiencing weird problems. For example, the following script:

我们有2台机器以这种方式安装,但最近我们遇到了奇怪的问题。例如,以下脚本:

clearstatcache();
if ( !file_exists($file_path) ) {
    return false;
}
//calc time
$mtime = filemtime($file_path);

Gives error:

filemtime() [function.filemtime]: stat failed for /var/www/XXX/954340789.2319_.html in /var/www/XXX.module on line 66.

filemtime()[function.filemtime]:第66行的/var/www/XXX.module中/var/www/XXX/954340789.2319_.html的stat失败。

I can't reproduce this error whenever I want, meaning it occurs randomly.

我无法随时重现此错误,这意味着它会随机发生。

Any suggestion how to try to deal with the problem?

有什么建议如何处理这个问题?
