Problem with Buffalo Terrastation TS3420R

[dmayna]

Hey everyone,
I recently set up a Buffalo Terrastation TS3420R and am having problems with permissions while using a linux machine. The NAS is configured and mounted to my machine but there is a problem when I try to use it. It seems to be there is some type of caching issue, if i cd into the directory and run a ls command it will periodically return
ls: cannot access trashbox: No such file or directory
ls: cannot access Network Trash Folder: No such file or directory
ls: cannot access Temporary Items: No such file or directory
If i cd into those directories and try to ls again then it works fine. I am able to create files and folders to the NAS but when I try to build one our applications it messes up the permissions
temporarily. For example, after trying to build our application and I run ls -l it will return 
ls: cannot access cmake: No such file or directory
ls: cannot access common: No such file or directory
ls: cannot access docs: No such file or directory
ls: cannot access host: No such file or directory
ls: cannot access prebuilt: No such file or directory
ls: cannot access target: No such file or directory
ls: cannot access thirdparty: No such file or directory
ls: cannot access aie_vectorizer: No such file or directory

Firmware is updated and currently has nfs and smb enabled. I tried restarting the NAS, using different protocols and manually mounting it to a different folder but nothing has helped the problem.
Any suggestions on how to fix this issue? Very much appreciated
