Bucket deletion stalls with orphan bucket

Will try to upload logs if I hit same issue, but for now easiest way to reproduce is to start cluster_run with 3 nodes and from testrunner directory..
./testrunner -i INI_FILE.ini -p get-cbcollect-info=True,get-coredumps=True,get-logs=False,stop-on-failure=False,GROUP=P1 -t fts.stable_topology_fts.StableTopFTS.index_query_in_parallel,items=1000000,num_queries=200,GROUP=P1

INI FILE is
[global]
username:root
password:couchbase
port:9000
[membase]
rest_username:Administrator
rest_password:password
[servers]
1:_1
2:_2
3:_3
[_1]
ip:127.0.0.1
port:9000
