A Tor instance running with `NumPrimaryGuards = 6` and `NumEntryGuards = 2` will report: ``` 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). ``` We expect to run with 6 primary entry guards and use 2/6 of them all the time, so it should complain about missing descriptors for 1/6 or our primary entry guards. Or maybe this param is not processed correctly and updated in the state file. When `NumPrimaryGuards` changes its value, we should sample more guards as primary in the existent state file, or create one if it doesn't exist with the right number of primary guards.
