Linux/Unix NFS bug

Sometimes it seems that we are not able to 'touch' the file becaue of error "already exists", but we try to delete it we get an error "file does not exists".

To solve this issue,
We need to create a temp file.
mv to original file
and then delete this file.

Now, we will be able to create a new file in same location.
