Adapter and Integrations links lost after import

Hello all,
I’m running WM Enterprise Server 4.1.1 on a HP-UX11.00 box.
The system is at the latest patch level.

I’m experiencing a problem during import:

After a broker_load operation I loose the links between adapters and integrations
In other words: I open Enterprise Integrator, I select an adapter and then “Relationship”. What I see is that he adapter doesn’t link any integrations.

I took this corrective action: I select the Integration Component and the related Tab “Properties” and then click on “Change Adapter” reapplyng the same and all become normal.

But I can’t do this for several hundred of Integrations.

Is there any know issue about that ?
Is there same other patch ?

Thank you very much,
