ORA-02067 error on Spring MVC / Oracle / Tomcat

Randomly my Spring MVC/Oracle 11G/Tomcat 7 application is throwing the following error: “ORA-02067: transaction or savepoint rollback required”

Once that error appears ALL subsequent operations to the database that uses that same connection through the Tomcat will fail throwing the ORA-02067 error.

Example:

"detailErrorInfo": "CallableStatementCallback; 
uncategorized SQLException for SQL 
[{call SCHEMAX.[PACKAGEX].PROCEDUREX()}]; SQL state [60000]; 
error code [604]; 
ORA-00604: error occurred at recursive SQL level 1
ORA-02067: transaction or savepoint rollback required;
nested exception is java.sql.SQLException: 
ORA-00604: error occurred at recursive SQL level 1
ORA-02067: transaction or savepoint rollback required",

Curiously, if I call that same Oracle package/procedure from other connection or application, it works.

The error stops only on the Spring application the moment the administrator restart the Tomcat.

My theory is there is a transaction that is failing and is not doing a rollback. Because the Tomcat is using a pool of JDBC connections, the error persists on the application.

I have not being able to reproduce that on the development environment.

Does Oracle provides tools to pinpoint the culprit transaction? Is there any view that display transaction that are pending a rollback?

Thanks
