      Description

      We're seeing Seg Faults when under high load. The first time this happened was when we were loading data from one collection to another. This caused the primary to crash and by the time we caught it had gotten too far behind the oplog on the other servers in the replica set. So, we dropped everything in the data dir and allowed it to resync. Now we're seeing the same "Invalid access at address" during the resync.

      The log file shows:
