    I'm not a DBA, and I have never used version 11g. These are just some ideas that came to mind when reading your question. -Have you reviewed the log files ? (application server logs, database logs, OS logs) -Did you make changes to the network besides changing OSes and Oracle versions ? -Are database links involved ? If so, are local and remote databases the same version ? -Have you reviewed all the errors you get, in order of occurrence ?

    yes , the dba reviewed the oracle logs and didnt find anything. after some tests with a similar enviroment, with some changes to db not disclosed to us yet, and alteration of the ip address of the linux oracle db cluster , we found out that the db sessions didnt die anymore. so it seems it was a network issue.
