      Description

      I tried to spinning up a new replica set from a previously unreplicated database. I upgraded to Mongo 2.4.0 on both machines. I killed the local.* files on both machines, restarted them with the replSet option, and then ran rs.initiate() and rs.add() on the second machine.

      Sometime during the synching phase, both servers crash. The secondary one reported:
