ORA-04021 is timeout occurred while waiting to lock object. Before that occurs, the session in question will be waiting. Is it waiting on 'library cache lock'? 'library cache pin'? Some type of mutex wait? Something else?

Subject: After 11.2.0.4 upgradge getting ORA-12012, ORA-04021, ORA-06512 errors on ETL job
OS - Solaris Sparc 10
Oracle - EE 11.2.0.4
We upgraded a dev database from 11.2.0.2 to 11.2.0.4. One of our ETL jobs started failing with errors ORA-12012, ORA-04021, ORA-06512. We have identified the object it is waiting to lock, but have no idea why this is occurring. The object is a partitioned table. The code did not change. I was told it creates a new table and does a partition exchange. I am not familiar with partition exchanges, but wonder if this might be where the issue lies. It also does some of it's work over a dblink to another database.
I've opened a ticket with oracle, but I've been give only until noon Monday to resolve or I have to downgrade the database. Can anyone point me in the right direction. My searches so far have told me only how to find the object in question.
Thank you.
