2009-10-10 10:14:35,390 [0xb61d4b90] - Cann't open the session!<br>
<br>
the network between client and server seems no problem (ping and it's alive)<br>
can someone give me some clues to locate the problem?<br>
</div></blockquote>
<br>
I am seeing the same problem after upgrading to omniORB 4.1.4. It never occurred in 4.1.3.<br>
<br>
It happens sporadically so I have no test case that can reproduce it reliably.<br>
<br>
If it is something introduced between 4.1.3 and 4.1.4 looking at the differences should give a hint. I tried this once but there were a lot of license changes, so you have to deal with a lot of "noise".<br>
<br>
Regards, Peter.<br>
