On production servers we have a mount point with NFS:
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:
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.
I can't reproduce this error whenever I want, meaning it occurs randomly.
Any suggestion how to try to deal with the problem?
