Why is my DB connect checkpoint value not updating?

Howdy Splunkers,

After creating a new database input through the DB connect GUI, the query keeps returning the same values, and the checkpoint value is not updating.

Log search:

index=_internal host=[db_connect_host] sourcetype=dbx_server DbInputCheckpointRepository

Log messages:

Despite running as "Local System", apparently Splunk was unable to update the file. I relaxed the security on this checkpoint file only, and now it updates no problem.
