| * cache-server as its endpoint. Primary does some operations and is stopped, the client fails over |
| * to secondary and does some operations and it is verified that the 'invalidates' stats at the |
| * client is same as the total number of operations done by both primary and secondary. The bug was |
| * appearing because invalidate stats was part of Endpoint which used to get closed during fail over |
| * , with the failed endpoint getting closed. This bug has been fixed by moving the invalidate stat |
| * to be part of our implementation. |
