    One of our production servers is throwing the following exception stack trace and we would like to elicit help in determining what might be the root cause of the error. The interesting parts of the stakc trace are: ava.lang.NullPointerException at com.mongodb.CommandResult.getException(CommandResult.java:64) at com.mongodb.CommandResult.throwOnError(CommandResult.java:116) at com.mongodb.DBPort.checkAuth(DBPort.java:308) Any thoughts on the root cause possibilities? The error is intermitent and not consistent.
