Yes - for crazyness' sake, rename the file you wish to update and drop a replacement file in it's place. See if the filesystem acknowledges you are serving a different file.
You might also look at EnableMMAP off which can sometimes have very similar symptoms to EnableSendfile. Bill Coulter, Ryan wrote: > I spoke too soon about "EnableSendfile off" not working.
