Please try with the snapshot from here:

http://omniorb.sourceforge.net/snapshots/omniORB-4.2-latest.tar.gz

(Or the latest from the 4_2 branch in SVN.)

That contains a fix for a three-way lock deadlock that is quite likely
to be the cause of your problem.

Let me know if the problem still occurs with that.

Duncan.
