Description

I got some ERROR messages on my slave server, during normal operations.

I'm not sure, but it looks like perhaps the fact that the host is dual-homed (IPv4 and IPv6) but only has the master configured on one address (IPv6) is causing problems.

The zonemgr IS running, and everything is working normally... except for those errors.

I have seen this often. See #2562. Maybe related to #2676.

Is your problem with recent master or 1.0.0 release?

(Another example is in #2636.)

comment:2 Changed 7 years ago by jinmei

I suggest increasing log level of zonemgr.

comment:3 Changed 7 years ago by shane

Okay, I've set the logging for Zonemgr to debug 99. Hopefully some more information will arrive. (So far it's just IXFR and refresh messages.)
