[Zope] Zope + omniORB4.0

[Андрей Пучин]

Could anybody help with next problem?

I have:
  Zope-2.5.0 under Windows XP
  Python 2.1.3
  Zope Product
  omniORB40 with omniORBpy
  APPSERVER (C++, TAO)

Cycle 1.
Step 1. Product's function (A) creates CORBA object (B) and transfers its object reference (C) to the APPSERVER.
Step 2. APPSERVER call methods of B through C
Step 3. A delete B and C

If Zope running with option -t 1 on 10 users all works great
If Zope running with option -t 10 on 10 users Zope suddenly stop responding after Step 1.

What's wrong?

Thanks,
Andrew
