Comment (by nickm):

 Wow; this is pretty tangled.  I find this hard to believe:

 > 4294682885 outbound circuits

 Do we have a counting bug?

 And this could be a bug:

 > Discrepancy in counts for queued destroy cells on circuitmux

 And this ''might'' show where stuff is going wrong:
 > n=317177. queue_size=317177. manual_total=317177.
 manual_total_in_map=32766.

 It looks as if, according to this, these destroy cells are never getting
 sent at all!
