[omniORB] Problem with a omniConnectionBroken

Fri Dec 13 20:50:03 2002

Hi,

I have a strange problem connecting to a servant (on the same machine), 
sometimes I get a COMM_FAILURE exception (very often) and others I don't.
My app is made of 12 omniorb (3.0.4.1) components running under 
GNU/Linux(2.2.20) all on the same machine.
I start all components, each component registers on OmniNames and then I run 
several clients (on the same machine), one of this clients calls a couple of 
methods on a component. The problem is that sometimes everything goes smooth 
with all clients and others I get the following trace always on the same 
client (but the component the client is contacting is up and running and 
later on other clients can connect to it without any problems). What can I do 
to solve this problem or at least minimize it?
