Hi,
This quite unpredictaable behaviour happen with webMethods Adapaters.I believe below is the reason for this
In case any changes are happened to connection parametes(edit or delete),Adapter service tried to make a lookup on the connection parameters in runtime or desgin time.it will through this exeception
All you have to do is toggle the connections.
I am not sure,we had fix for this or not.Please check Adapater Developement guide for more information.
Also,correct me if am wrong
Thanks
Sai.
