EXISTS error code

[Chris Rendall]

 We are running filePro 5.0.14 on Linux.  I have a directory path in Linux mapped to our Windows 2012 R2 file server.  Recently I had to make a change on the file server, but the mapping to the shares from Linux to Windows still works.  Our Linux server is still able to connect to the Windows share, but the 'exists' command in filePro that was been working for years has now stopped working and gives me an error -22 when checking if a file exists on the Windows share.

I commented out the 'exists' command and the variable with the path to the PDF works when the WINSTART command is echoed to the screen in AnzioWin, so I know the mapping from our Linux server to the Windows file share is working. 

Does anyone know what a -22 error code means when running the 'exists' command?
