ServiceCreationException exception: Cannot get the member 'segment7'.

Hi,

I am using BizTalk Server 2006 R2.

I have an orchestraion with a long running scope, which in some situations may wait for couple of hours for responses on a receive shape, and this is why it may be dehydrated to the messagebox for couple of hours.

When re-hydration occurs, In some rare situation I get the following exception:

This is the error:

I have no idea what is member segment7, it's not a class member in any of my code.

This exception doesnt happen all the times, just once in a while in this scenrio.

I would appreciate any assitance.

Thank you,
