timeframe?
dgoulet:
That's a good question I don't have an answer for.
Unfortunately, I don't think that's the kind of message that occurs
multiple times, looking at #30746 (and friends) this seems to be able to
cause havoc with just a single repeatition.
I'm not sure why this is the case, since `router_have_minimum_dir_info()`
seems to be called all the time and that should eventually call
`entry_guards_get_err_str_if_dir_info_missing()` which is the source of
the log message... Things are kinda messy between these two functions tho,
so it's kinda hard to understand what's the issue.
Perhaps we can merge this patch for now since it does not seem to make the
situation worse, and we can think in the future how to improve the UX? If
you agree, feel free to toggle this into merge_ready since the patch LGTM.
