---------------------------------

             Summary: Should we avoid loading HostDB disk file is sync_frequency is '0' (disabled)
                 Key: TS-4929
                 URL: https://issues.apache.org/jira/browse/TS-4929
             Project: Traffic Server
          Issue Type: Improvement
          Components: HostDB
            Reporter: Leif Hedstrom


This addresses two issues:

1) We get warnings trying to load a non-existent HostDB (since we don't sync it).

2) Worse, if someone has an old HostDB, that is no longer synced / updated, we load the old, possibly stale, data on every startup.

#2 seems inconsistent with the other changes to HostDB, where now the sync frequency =0 truly turns off disk syncing.
