Has anyone found the list() method of Query to block?

I run my application on the server (JBoss) and the following query will block after it has been called a few times:

Code:
@NamedQuery(name = "User.findByUsername", query = "FROM User u where _username = :userName"),
....
query.list()


I can't see any database locks and the CPU doesn't max out. When I turn on SQL logging, I don't even see the generated SQL for this query when it blocks.

However, when I run my application on my local Tomcat instance (connecting to exactly the same database), everything is fine.

Any ideas?

It might be nothing, but when the query.list() eventually returns I see the following entry in the server log:

Code:
2010-04-28 09:24:11,783 INFO  [STDOUT] query.list() finally returned!!!!!!
2010-04-28 09:26:00,263 INFO  [com.adobe.idp.um.businesslogic.dao.hibernate.UMLocalSessionFactoryBean] Using dialect [org.hibernate.dialect.MySQL5Dialect] - Detected DB Product name - MySQL and version 5
