We are using Weblogic 7.0 and we have clustered servers. When we doing longevity test, I noticed that my EJB method is called twice (log statements are printed twice in 10min gap). Same time the EJB method called first time taking more time to complete the execution. Can you give some tip, why I am getting this problem? I want to know, whether it is related to ������Replication and Failover������in cluster environment.
