 Here is the config from the Tor client where the crash is happening:

 The configs used for the servers in this network can be found here:

 I'd also be keen to hear if the configs I have for such a network actually
 make sense, and that I haven't forgotten something crucial when testing
 Tor.

 Thanks

Comment(by nickm):

 Hm.  So it looks like the fix is to make it so that
 CONSENSUS_MIN_SECONDS_BEFORE_CACHEING gets scaled down on private networks
 with extremely low voting intervals.

 mwenge, would you agree?
