Raj,
I'd like to see how you used to create the KieSessions before.

If you just did:
KieContainer.newKieSession()
that might not work

You should instead be able to do:
KieBase.newKieSession(),
but create the KieBase only once, not every time you need a
KieSession (assuming that all sessions will essentially use
the same rules)

The way you do it now works, but has a heavy impact
on performance, since you recreate the KieBase every time.

Hi  Davide/Wolfgang

The problem is resolved by establishing the session from Kiebase

KieContainer kc = KieServices.Factory.get().getKieClasspathContainer();

KieBaseConfiguration conf =KieServices.Factory.get().newKieBaseConfiguration();

KieBase kieBase = kc.newKieBase(kBaseName, conf);

ksession=kieBase.newKieSession();

No more errors are seen in the log. Kiebase is thread safe. Regards, Raj

Hi 

Thanks a lot Wolfgang 

Actually i have 2 bolts 1 bolt gets inserts the facts emitted by sprout and  other bolt inserts data into the database. yes 1 bot per fact 

regarding losing session i mean that does the KieSession(6.0) works in a current technology  stack  which i am using currently using strom - drools- saving back to database.

Regards,

Raj

+1 Wolfgang :)

Raj,
we'd need to know things like: how many bolts, how many knowledge bases
(I guess one),
how many kiesession - a singleton, one per bolt, one per batch of facts...?
Also, "losing the session since it's running in a multi-threaded
environment" - what does
it mean exactly?
Thanks
