Name and version of the database you are using: Oracle 9.2.0.6, pooling via DBCP

Hi,

we are facing an endless loop in LoadContexts.cleanup(). As you can see there are only 2 ResultSets which should get cleaned, but they were never cleaned and live forever in the collection. This generates a fair amount of CPU time and our logs look quite horrible....

Can anyone give us a hint whats wrong there. It just happens at some certain point of time and then it never ends. Who is triggering the cleanup? DBCP?
