Comment (by s7r):

 Still getting it often in `Tor 0.4.1.2-alpha-dev` on a service that is
 configured with `NumEntryGuards = 3`:

 {{{
 Sep 05 03:22:50.000 [notice] Our directory information is no longer up-to-
 date enough to build circuits: We're missing descriptors for 1/3 of our
 primary entry guards (total microdescriptors: 6515/6541).
 Sep 05 03:22:50.000 [notice] I learned some more directory information,
 but not enough to build a circuit: We're missing descriptors for 1/3 of
 our primary entry guards (total microdescriptors: 6515/6541).
 }}}

 If `NumEntryGuards` is > 1, and we have descriptors for at least 1 primary
 entry guard, shouldn't it be possible to still build circuits? It's OK to
 complain about not having it yet in the log file, but I think we should
 still be able to build circuits. This is the purpose why one would raise
 `NumEntryGuards` from 1 to some higher value, to gain better connectivity
 against greater probability of running into a hostile guard.
