I am getting the following error in the database logs :
ORA-00604: error occurred at recursive SQL level 2
ORA-01003: no statement parsed
which then leads to a ORA-4031 error.

I found a doc that says that I might be hitting Bug 3289063
ORA-1003 every 5 seconds after CJQ hits ORA-4031

The workaround for that bug is to recycle the CJQ process.
