Hi,

Iam using the Jboss EAP 4.3 Hibernate jars which are versioned 3.0 . I have an transaction which slowly runs out of the memory when run over a long period of time.

In this app am persisting an Hibernate object to the database . The hiberante object contains a blob . Am suspecting this could be the leak . Profiling points to be the byte[].

This is how i persist the blob
Blob blob = Hibernate.createBlob(byteStream)
MyPDO.setDocumentBytes(blob);
myDAO.makePersistent(myPDO) ==> writes to the DB.

Any suggestions would be helpful if the Hibernate.createBlob is leaking or not . Thanks in advance.

Any Ideas regarding Mem Leaks.

If you have caching enabled, then hibernate managed objects that contain a massive byte array are cached in memory.

Try disabling the hibernate caches, if your DB is well tuned it and there's not a lot of overhead with marshalling the results from your reports then you should notice very little performance degradation.
