    Description

      I am trying to upgrade a 2.6 sharded cluster (with auth enabled) to 2.7.8-pre (git hash 0b336ddb1e0ede7a9a381b510b4de344daadc307).

      When I take down the first 2.6 mongos, and restart it using the 2.7.8-pre binary, I get:

      $ /tmp/mms-automation/test/versions/mongodb-osx-x86_64-0b336ddb1e0ede7a9a381b510b4de344daadc307-2014-10-17/bin/mongos -f /tmp/mms-automation/test/versions/workspace/mongos-mongosAU_SH1.conf --upgrade
      about to fork child process, waiting until server is ready for connections.
      forked process: 80424
      ERROR: child process failed, exited with error number 1

      with the following in the logs:

      This was working fine with git hash 8ef589d359bcb57db83c5d53f1608afbf5b79a01 and has been broken since at least 126069374744c62c65fac86a492531d658961f40.
