hey, what a wonderful occasion to get your hands dirty, isn't it ? :-)

I think your guess isn't that far off, though "it's a bit more complex
than that". The ORB has a couple of mechanisms to protect itself against
concurrent shutdown. Calls like POA destructions and ORB shutdowns are
usually (i.e. when called with the correct parameters) deferred such
that the ORB can make sure that nobody is executing the relevant code.

But other than that, yes, the error message definitely sounds like
a premature termination of the ORB. If you need any help in debugging
this, just ask.

sounds like a bad side-effect of the above error.

Do we have a bug for these symptoms ? If not, would you
mind filing one ?
