Vault reading excessively from disk (1TB in 6hrs with a 2MB filestorage db)

Has any one noticed vault reading excessively from disk?
I have a single instance 2MB filestorage db and in 6 hours of uptime with basically no use vault read 1.1TB of data from disk.
Running version 1.12.2.

This is a container image. podman stats is where I am getting the data read number. I can also observe it in atop.
