<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">We are using OmniOrb since a very long time (since 2.80) and we are facing a very strange problem in a very strange configuration.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>

</span></span><![endif]>Context<o:p></o:p></p>
<p class="MsoNormal">On Windows Server 2008 R2 or Server 2012 SP1with 2 NICs, we have a service called TaskServer.<o:p></o:p></p>
<p class="MsoNormal">All CORBA dlls are built with MSVS 2012.<o:p></o:p></p>
<p class="MsoNormal">All wrapper for CORBA are coded with C++ MSVS 2012.<o:p></o:p></p>
<p class="MsoNormal">All other dlls are coded and built with C# MSVS 2012.<o:p></o:p></p>
<p class="MsoNormal">The service is coded with C# MSVS 2012.<o:p></o:p></p>
<p class="MsoNormal">The .Net Framework is version 4.<o:p></o:p></p>
<p class="MsoNormal">IPv4 only protocol. (but the same if we mix IPv4 and IPv6).<o:p></o:p></p>
<p class="MsoNormal">CORBA config has no fix name nor port.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>

</span></span><![endif]>Problematic<o:p></o:p></p>
<p class="MsoNormal">The service is using .Net Remoting technology to listen for orders (task).
<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">When we demand a particular task, it loads dll. When the dll are using CORBA 4.1.7 for achieving their duty, it always shutdown the .Net Remoting socket as soon as CORBA load.<o:p></o:p></p>
<p class="MsoNormal">The exception in socket .Net remoting is silent. The service never received any message or exception into any .Net callback function<o:p></o:p></p>

<![if !supportLists]><span style="mso-list:Ignore">-<span style="font:7.0pt "Times New Roman"">
</span></span><![endif]>Test, conclusion and Workaround<o:p></o:p></p>
<p class="MsoNormal">This never append in 2.8 and MS Visual Studio 6.0 (we tested it).
<o:p></o:p></p>
<p class="MsoNormal">This never append if only one NIC is used.<o:p></o:p></p>
<p class="MsoNormal">We have no problem if we force the TaskServer to load CORBA 4.1.7 prior to lunch .Net remoting listener!<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Can Anyone help me to go deeper into this since we receive noting from C++ driver using CORBA 4.1.7 or from CORBA itself.
<o:p></o:p></p>
<p class="MsoNormal">We receive nothing at the TaskServer service in C#. Only the debugger write down a trace about the socket exception but we do not have the symbols or the code.<o:p></o:p></p>
