The strange inexistent FQDNs in the bpdbm.logs
Enviroment: NBU 8.1.1 on RHEL 6.9
Symptom:
1) There are many hostname resolution entries about the vnet_cached_getaddrinfo with their inexistent FQDNs in the bpdbm.logs:
Notes: They are the host short-names used by the master/media server in the bp.conf, those are also resolved via the /etc/hosts.
