[b]Hibernate version:2.1.1

I encounter a weird problem. I am using hibernate for 2 months. Everything is fine until yesterday.

The hibernate would drop my existing jbpm tables and regenerate the table. And all my data has gone. I have to recover database from time to time.
Does any one ever encounter this problem?

Also hibernate team, what is the relationship between this config with create-drop tables?

hibernate.hbm2ddl.auto=create-drop|create|update

I did not specify this configuration on the hibernate config. What is the default value for this config item?

How to forbid hibernate to drop tables and recreate tables automatically?

Thanks!
