Hi...
We are using DSpace 6.3 (XMLUI, modified Mirage2 theme).
I reported a problem with indexing OAI recently.  I get an
error "org.hibernate.exception.JDBCConnectionException: could not extract
ResultSet".  The database logs says things like:
"org.hibernate.TransactionException: commit failed" and "SQL Error: 0,
SQLState: 08006" and "An I/O error occurred while sending to the backend."
Now, I am seeing an error when we run filter-media.  This has been working
fine for a long time, and now, it is failing with:
Exception: rollback failed
org.hibernate.TransactionException: rollback failed at
org.hibernate.engine.transaction.spi.AbstractTransactionImpl.rollback(AbstractTransactionImpl.java:215)
(large stack trace afterwards)

Also, I saw problems running some of my local perl scripts that gather data
from postgres.  I have scripts that build reports about submission and
downloads, and occasionally they are failing with similar hibernate errors.

I have a feeling that this is all connected, but not being a DB Guru, I
don't know what could be happening here.  I would appreciate any
suggestions from the community.
