It is possible that the replication subsystem on the secondary is holding the global X lock when the mongo shell attempts to run the dbHash command. One option would be to retry the dbHash command as it should eventually succeed once the global X lock is released. Another option would be to wait for the secondary to have caught up to the primary as the oplog applier thread would then be idle.
