    Description

      During load tests there were several cases of node crash:

      File "/usr/local/lib/python3.5/dist-packages/plenum/server/node.py", line 1880, in allLedgersCaughtUp
    replica.caught_up_till_3pc(last_caught_up_3PC)
File "/usr/local/lib/python3.5/dist-packages/plenum/server/replica.py", line 2497, in caught_up_till_3pc
    self._remove_stashed_checkpoints(till_3pc_key=last_caught_up_3PC)
File "/usr/local/lib/python3.5/dist-packages/plenum/server/replica.py", line 2586, in _remove_stashed_checkpoints
    del self.stashedRecvdCheckpoints[self.viewNo][(s, e)]
KeyError: 28

      This bug was quick patched, but it seems that original code had typos, so further analysis is recommended, probably spivachuk can help here.
