    Description

      Build : 7.0.0-5017
      Test : -test tests/integration/cheshirecat/test_cheshirecat_kv_gsi_coll_xdcr_backup_sgw_fts_itemct_txns_eventing_cbas_scale3.yml -scope tests/integration/cheshirecat/scope_cheshirecat_with_backup.yml
      Scale : 3
      Iteration : 1st

      In the 1st iteration of the longevity system test, seeing 8 rebalance failures due to the below mentioned errors. The error is similar to what was seen in MB-44949. But since there are 2 indexes (bucket7:idx2_eWDiG bucket7:idx1_Nz4KQ) repeated in most of these error messages, it would be good to see if the underlying cause of these issues is same as MB-44949 or is this a different issue.
