Axis2 not access to db after several requests

   Hi all,

     Since several weeks ago i am having pretty big problems with my Ws on Axis2 1.6.2 i´ll try yo explain in few words:

    I have a Ws deployed on Axis2 that access an Oracle database in order to retrieve info.

    I built a jar which encapsulates access to databse, i mean i create a jar in which i implement a connection pool.

    To make this connection pool i used DBCP 1.4. My server is Tomcat 6 and i use Java 6 on HP-UX

     After making several requests to my Ws it starts to fail. I put several logs in order to know step by step when it fails and i found that it fails the first time a request need to access database, and this only happens after severral request (sometimes 20, sometimesm 8000 and sometimes two weeks after)

    I thought it was connection pool problem (maybe some dbcp issue) so i change my jar and start to use the framework BoneCP which i found works faster.

    I got same problem, do anyone have any idea? Because i´m becoming crazy, it fails also in Pro environment and i have to watch it almost 24 hours because it´s an important ws

    Any idea will be welcomed

 Thanks

Kind regards
