Jason/Wido, et al:
I was hitting this exact problem when attempting to update from 14.2.11 to 14.2.12. I reverted the two commits associated with that pull request and was able to successfully upgrade to 14.2.12. Everything seems normal, now.
Thanks,

Subject: [EXTERNAL] Re: 14.2.12 breaks mon_host pointing to Round Robin DNS entry
This backport [1] looks suspicious as it was introduced in v14.2.12
and directly changes the initial MonMap code. If you revert it in a
dev build does it solve your problem?
