    Description

      Build
      4.5.0-1924

      Testcase
      ./testrunner -i INI_FILE.ini get-cbcollect-info=True,get-logs=False,stop-on-failure=False,index_retry=10,GROUP=P0 -t fts.moving_topology_fts.MovingTopFTS.warmup_during_index_building,items=30000,cluster=D,F,F,GROUP=P0

      Steps:
      1. D,F,F cluster.
      2. When index starts building, soft restart couchbase server on one of the fts nodes (.190)
      3. wait for 60s after restart and then start polling for index count. Wait till it reaches bucket count(30K)
      4. Do another validation call to check the index count, it shows 27K.

      Logs from .190 or .66 - the 2 fts nodes do not explain why the index count goes down.
