Description
Steps to Repro
1. Run the following longevity on 6.6.2 for 3-4 days
./sequoia -client 172.23.96.162:2375 -provider file:centos_third_cluster.yml -test tests/integration/test_allFeatures_madhatter_durability.yml -scope tests/integration/scope_Xattrs_Madhatter.yml -scale 3 -repeat 0 -log_level 0 -version 6.6.2-9588 -skip_setup=false -skip_test=false -skip_teardown=true -skip_cleanup=false -continue=false -collect_on_error=false -stop_on_error=false -duration=604800 -show_topology=true

2. We have 27 node cluster in 6.6.2
3. Add 6 nodes(1 of each service - 7.0.0-5226) and remove 6 nodes(6.6.2) and do a swap rebalance to upgrade the cluster.
4. Failover 6 node(1 of each service - 6.6.2), upgrade, do a recovery and rebalance.
5. Tried to continue those steps for the rest of the nodes in the cluster, but one of the rebalances failed as shown below.
