I am seeing the same problem after upgrading to omniORB 4.1.4. It never 
occurred in 4.1.3.

It happens sporadically so I have no test case that can reproduce it 
reliably.

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".

Regards, Peter.
