[Samba] NT_STATUS_OBJECT_NAME_NOT_FOUND randomly

Hello Samba list,

we have a weird problem that occurs randomly when accessing file in a 
subfolder.

When opening the file (specifically a PDF) it works sometimes, but 
sometimes it only gives NT_STATUS_OBJECT_NAME_NOT_FOUND in the logs and 
"The Directory name is invalid" in Windows, though the file is available 
and opened fine a few seconds before. A few seconds later it will work 
again. In the following log example it didn't work for the first 7 
tries, the eight worked and the ninth didn't again, though nothing 
changed on the file nor the system itself.

When I put the file itself or the last subfolder in in the shares' root, 
the problem does not occur.

Does everyone here have an idea which could cause such behaviour? I 
thought of Windows caching, but nothing changed on the file, so the 
cache should always have the correct data to access the file. Also 
Windows asks for the right file as seen in a packet capture (Create 
Request File: "correct path", Create Response, Error: 
NT_STATUS_OBJECT_NAME_NOT_FOUND)
Next try: (Create Request File: "correct path", Create Response File: 
"correct path) => Works
