This is a bug in Biztalk. Whenever u have an orchestration that consumes
a webservice that return a string (or maybe any simple type),
undeploying any other orchestration on the same box cause the
orchestration that consumes the WebService to stop working. This, I
think is because the undeployment deletes subscription record from the
schema table in the BizTalk management database. Only the workaround I
know is to re-deploy the orchestration that consumes the web service.
Hope this helps.
