I am using Hibernate 3.3.1.GA and initializing it through Spring to write to an Oracle9i database. I am working on an application that uses Quickfix/J to connect out to a fix engine and retrieve trades. Before processing trades we must save off the markets. We are just marshaling the fix message into an object and save it out to the database to be processed by another app. When I just run the app with just logging everything and not calling save() it all runs fine. But when I try to save it to the DB I get this OutOfMemory exception. I have tried simply increasing the memory maximum, I had it to 2G but when viewing the app it at worst when I queue up all of the messages it only consumes 700k but still throws this error.
Exception in thread "QFJ Message Processor" java.lang.OutOfMemoryError: PermGen space

Using Spring obviously I don't manage the sessions myself, and in the dao all I do is pass it a market object and call
<bean id="dataSource"
class="org.springframework.jdbc.datasource.DriverManagerDataSource">
<property name="driverClassName">
<value>oracle.jdbc.OracleDriver</value>
</property>
<property name="url"><value>jdbc:oracle:thin:@127.0.0.1:1521:xe</value></property>
<property name="username"><value>${hibernate.connection.username}</value></property>
<property name="password"><value>${hibernate.connection.password}</value></property>
</bean>
