Getting nfsd non-standard errno -107

One of my docker containers stopped responding and after checking the log for the contianer, found it couldn't access it's data file which is stored on the cache drive.

Checked the kernel log and the following was at the end of it

First time it's happened to me so I have no idea where to start.
