[jacorb-developer] what orb property to change to avoid server running out of threads?

[David Rodenbaugh]

I am getting the error below after I upgraded from jacorb 2.3.0 to any of 3.0, 3.5, and 3.6.1.  A server process throws this error after a transient client command is invoked around 500 times in quick succession.  The client sends a message to the server and the server sends a response.  The client exits after sending a message to acknowledge the response.  I think the server is leaking the threads that handles the message from the client.  My orb properties are set the same as in 2.3.0 where this works, but I'm guessing I need to tweak a property for the newer versions of jacorb where I'm having the thread leakage issue.  I experimented with setting jacorb.connection.delay_close=off, and that worked longer, but still failed after 999 command invocations.  Any other suggestions for properties to tweak to get around this issue?
