          Suspect some environment issue. Request to retest in the same environment with build 4874. And then repeat the test with 4908/4910.

          As discussed with Gautham Banasandra , Jeelan Poola its not an environment issue, with 6.5.0-4908 we start adding lcb error + n1ql error in the stats. Previously if we get n1ql error we only increment for those. Hence these error start showing suddenly.
