      Description

      sshd limits number of simultaneous unauthenticated connections via MaxStartups configuration parameter. By default, 10 connections are allowed.
      sanityn/test_77* 's actor nrs_write_read() tries to run up to 32 do_nodes() in parallel, causing sshd to drop some of connections.
