Exception whilst load testing

Mandy,
I've run into this as well. It ONLY occurs when we're doing load testing
too. I guessed that it was some sort of timing issue accessing a socket
that had been closed or something...
This may seem like a strange question, but did the tests indicate an error
on the clients? Our tests did not, which indicated that the error was
(perhaps) handled internally.

Hi,
I am load testing 4.0.3 against JDK1.1.7 and notice that under heavy
load (18 processes each with 10 threads running the same test), I get
the following exception..

I don't see this if I put the load down to 10 processes so am concerned
why this might be happening. Our production server is currently running
Weblogic 3.1.8 under JDK 1.1.6 and I know I need to upgrade to version
4.0.x but want to ensure I pick a stable version. Would you definately
recommend 4.0.3 over 4.0.2?
Any help appreciated
Thanks

Hi Russell,
In our case the exception does get propogated to the client. I've traced the
problem down to the following line:
e = postInvoke(current, newTx,
((EJBSpnAPIBeanHomeImpl)ejbHome).md_getRule
GraphFileSummaryForSpn_SpnKey, e);
I think.
Has anyone else had similiar issues? Again, all works fine under 3.1.8 so I'm
reluctant to upgrade.
Mandy
