How disconcerting. The exception is being thrown by the JDBC driver
and is most likely something to do with connection pooling. Looks
like you should disable C3P0's prepared statement cache. (Or
try some other connection pool implementation...)

[EMAIL PROTECTED] Subject: [Hibernate] DeathMarch Error
Message

05/02/03 06:55 AM
I'm new to Hibernate and am getting a strange error when saving an
object to the database. The save is happening, but an error of
"java.lang.RuntimeException: Internal inconsistency: A (not new)
checking-out statement is not in deathmarch." is alarming. Do I need
to worry about it?
