slony replication issue

I use slony version "slony1-1.2.20" , and postgresql version 9.1
I am using slony replica Master DB to Slave DB
The issue I got , when I created cluster on Master DB , then insert one row for the replica table , it will got below log , But if I drop the cluster , it can do insert ,delete and update . Can you help me to solve out this issue . I have attached the cat cluster_setup.sh script. Again , I have not started to test replica .
