SEGV crash in rfa::sessionLayer::SessionImpl::dispatchResponseProcedure

We are using RFA C++ 8.1.0.L1 on Linux RedHat 6.10. We see the following SEGV crash:

Based on the call stack it's quite hard to tell possible root cause because of it just a normal dispatch call inside RFA.

-Can you replicate the issue on demand? or It occurs just once and cannot replicate it again.

This kind of question required an in-depth investigation. We need more information about your use case and your implementation. Not sure that, what kind of RFA application you are using and how many session and event source in your application. Do you have multiple thread call dispatch to the same event queue?

We would suggest you contact one of the RDC named users within your organization to open a case to investigate the issue further.

Thanks @moragodkrit. The issue is intermittent.

We have multiple threads calling dispatch, but each has its own unique event queue object, although each event queue has the same name. Could this be an issue?

As far as I understand, if we create a new event queue with the same name, RFA internal just create a new instance of the event queue and then append the number to the name. In my point of view, this should not be an issue.
