deadlock while perform JDBC operations?

Hello,

We are running Weblogic 7.0SP2 with Oracle 9.2.x as the db.
We use Oracle for TOPLink as our orm tool for all db access.

We are encountering strange deadlocks while doing db reads and updates from a
message-driven EJB (MDB) whose onMessage() method has a "Required" transaction
attribute.

I have attached a partial thread-dump below. It seems that multiple threads (3+)
are waiting to lock the same monitor:
- waiting to lock <39f68f0> (a oracle.jdbc.driver.OracleConnection)

This is strange as each thread is running in its own transaction, and so it should
be using a unique jdbc connection. btw, we use a Weblogic Connection Pool. The
TOPLink orm tool obtains a connection from the pool by using the DataSource.getConnection()
method.

My confusion arises from the fact that some threads are locked while performing
read operations and for some reason are waiting to lock the same monitor.

Any help will be greatly appreciated.

p.s. i also verified that there are more connections available from the pool,
and idle ExecuteThreads while the deadlock occurs.
Eventually, the transaction times out and gets rolled-back.

You will need to show more of the thread dump. Specifically, we need to see which
thread(s) *have* the connection locks, and why they are stalled.
