 Post subject: HIbernate: Cascade during flush is dangerous

I am having a Batch process which processes a file and inserts records from the file into database. I have two environments dev and production. This process always works fine in Dev but sometime fails in prodcution environment throwing the below error:

"Error in inserting data in table:::org.hibernate.HibernateException: Flush during cascade is dangerous."

I am not able to undertand where this logic is failing and that too sometimes.

My code is:

int count =0;
try {
foreTime = Functions.getDate(record.getDateTime(),"dd/MM/yyyy HH:mm");
targetDateTime = Functions.getDate(record.getTargetDateTime(),"dd/MM/yyyy HH:mm");
logger.debug("targetDateTime:" + targetDateTime);
} catch (Exception e) {
logger.error("Error while validating date");

if (errorFlag == false) {
logger.info("inserting into database");
try {

foreData = new ForeData();
compoundKey = new ForeDataCompoundKey();
compoundKey.setForeTime(Functions.getDate(record.getForeTime(),"dd/MM/yyyy HH:mm"));
foreData .setKey(compoundKey);
foreData .setForecastWd0(Record.getWindDirection0());
foreData .setForecastWs0(Record.getWindSpeed0());
updateData(foreData,fileName, session);
if (++count % 1000 == 0) {
output.info("updating the database");
// tx.commit();
} catch (HibernateException e) {

errorMessage = sqlEx.getMessage();
errorCode = sqlEx.getErrorCode();
message = "Error in inserting data in table";
throw new QueryException("Exception occured");

and updateData(foreDtaa, filename , session) method is like:

updateData(ForeData foreData, String fileName,
Session session) {
try {
IHibernateDAO<ForeData, ForeDataCompoundKey> dao = (IHibernateDAO<ForeData, ForecDataCompoundKey>) SpringUtil

} catch (Exception ex) {


and saveNoFlush() method is:

public T saveNoFlush(T entity) throws QueryException {
try {
// Transaction tx = session.beginTransaction();

// tx.commit();
return entity;
} catch (Exception e) {


Can you please look into it and tell me why this error is coming up and that too intermittently?
