From time to time I have an issue where users report they cannot move or rename a file, getting the error that it is currently in use. I have checked the file server, and no active sessions exist pointing to these files. I have also tried to use "Unlocker" software to forcefully close any open connections to the files, but the software says there are no locking handles on these files. The only way to get these files to cooperate again is to reboot the file server.
Does anyone have an idea what might be going on here?
