I was able to replicate this issue by changing the user ID of the
traffic_server process. There is a hidden file that stores some additional
HostDB information and if that can't be written the host.db never gets
successfully reconfigured. Once I removed the hidden file and made sure the
directory permissions matched the ATS user, the host.db was reconfigured
successfully. Removing host.db caused a single start to reconfigure and
subsequent restarts had no issue.
Check the file etc/trafficserver/internal/hostdb.config and the containing
directory to see if that is the problem. In particular that both are owned by
'ats' and not 'nobody'. However, when I did this I got a message in diags.log
about the permission denied on that file.
