There's a database table (2000 records in it and has 2 BLOB fields).
We started to get OutOfMemory Exception from NHibernate. Is it because the record count and BLOBs? If so what can we do?

CREATE TABLE DOCUMENTS
(
ID NUMBER NOT NULL,
PARENT NUMBER,
NAME VARCHAR2(4000 BYTE),
FILENAME VARCHAR2(200 BYTE),
PATH VARCHAR2(4000 BYTE),
DESCRIPTION VARCHAR2(4000 BYTE),
REVISION VARCHAR2(32 BYTE),
DISPLAYDATE DATE,
DOCUMENTTYPE NUMBER,
PROJECT NUMBER,
DELETED NUMBER,
CREATEDBY VARCHAR2(512 BYTE),
CREATEDATE DATE,
UPDATEDBY VARCHAR2(512 BYTE),
UPDATEDATE DATE,
PO_VALUE FLOAT(126),
DATE_ORDERED DATE,
FIRST_SHP_DATE DATE,
YD_NO NUMBER,
YD_VALUE FLOAT(126),
BECHTEL_SCN_NO VARCHAR2(512 BYTE),
FILE_CONTENT BLOB,
INVOICE_DATE DATE,
DOCUMENTATION_DATE DATE,
COC_DATE DATE,
CONTRACTUAL_PAYMENT_DATE DATE,
ACTUAL_PAYMENT_DATE DATE,
FILE_CONTENT2 BLOB,
FILENAME2 VARCHAR2(200 BYTE),
ARCHIVED CHAR(1 BYTE)
)
