Current Behavior

When running in a kubernetes-cluster, the initialization of a pod skip updates and attempts update of IPs every few seconds, and then periodically fails with

Setting up watches.
Watches established.
WARNING:  skipping update of foo.bar from <nothing> to xx.xx.xx.xx.
WARNING:  last updated <never> but last attempt on Fri Feb 24 17:08:45 2023 failed.
WARNING:  Wait at least 5 minutes between update attempts.

WARNING:  last updated <never> but last attempt on Fri Feb 24 17:08:48 2023 failed.
WARNING:  Wait at least 5 minutes between update attempts.

Those lines keep repeating, but after a certain time, another failure message is shown:

FAILED:   updating foo.bar: unexpected status (15)
Use of uninitialized value $h in hash element at /usr/bin/ddclient line 4316.
Use of uninitialized value $_[0] in sprintf at /usr/bin/ddclient line 2160.
WARNING:  updating : nochg: No update required; unnecessary attempts to change to the current address are considered abusive

Seems like the updates are working though. Looks like all of this is an issue with ddclient not properly caching previous update attempts.
