[Bug 1668410] Re: Infinite loop trying to delete deleted HA router

[Basel Darvish]

a single infinite loop message has filled up disk space by logs in 6
hours. 50 such messages within 10 minutes (still not many enough to be
throttled by a regular configuration of a rate-limiting proxy) could
have filled up the disk a lot faster leaving no time for operators to
react.
