> When NiFi starts, it tallies the count of how many FlowFiles reference each 
> Resource Claim and then removes or archives any file in the Content 
> Repository for which there is no claim.
> However, the claim counts are not incremented for data that is swapped out. 
> As a result, the content repository could delete or archive data on restart 
> that it should not. This could potentially result in data loss, if NiFi is 
> restarted while both of the following conditions are met:
> * All FlowFiles that reference a Resource Claim are swapped out
> * Content Repository's archive is disabled, or the archival threshold is 
> already exceeded from data outside of the Content Repository
