Update of bug #18407 (project freeciv):
Status: None => Confirmed
_______________________________________________________
Follow-up Comment #2:
Reproduced with 2.3.0-RC1 and head of S2_3 (r20165).
Looks like it's spending much of its time in auto_arrange_workers() and
minions after Brussel / Bruxelles grows from size 50 to size 51.
Are megacities like this exposing bad computational complexity in our
algorithms?
A couple of backtraces from aborting the server during the delay
(2.3.0-RC1):
