[ubuntu] Errors in boot up topic

Hi, I am running ubuntu server (latest version) and am seeing this error on start-up. Note that my CIF shares work but I am not sure where these are coming from?

Code:

---

CIF shares work fine but I do also get this now:

Code:

---

[  812.465179] CIFS VFS: No writable handles for inode

I am also seeing a service related error but not sure where to look to resolve?

Code:

---
