[omniORB] Getting a debug assertion error while trying to shut down a corba server.

[Mike Bendickson]

Yes, NP_destroy() does return.

After execute impl_shutdown(), [CORBA:BOA::impl_is_ready] thread is killed.

After execute orb->NP_destroy(), [omniORB_Ripper::run_undetached] and
[omni_Scavenger::run_undetached] are killed.

Then when trying to go one further step in our CORBA server thread (which
should return to main), assertion failure.

We modified our project to create a static library instead of a DLL, and the
problem went away.

Any suggestions?

Calling impl_shutdown() from another thread is the right thing to do.
You said NP_destroy() executes as expected, does this mean that you are
getting the assertion failure after NP_destroy() returns? In your code
there may be object references or implementations being deleted after the
ORB has been completely shutdown. This of course results in unpredictable
behaviour.

Another point to check is whether your code works if you are not using the
DLL loading mechanism.
