FW: ServiceCreationException-Failed while creating a EA_CostCenterList.EACostCenterList servi

I got the following error after successful deployment of assemblies in BizTalk. I have BizTalk installed in federated (distributed) way. 4 BizTalk servers associated with same deployment and I have to install orchestration assembly in one server and gac it all other servers. after installing and gacing when it starts processing I encountered unique and weird problem. some time my orchestration picks up message and some other time throws following error.

When I checked the installation logs there was no error and also checked whether the orchestration was present in the gac on all the servers and it was there.
So there is something must happened the way it was installed which made BizTalk engine to run the orchestration on and off mode.
And finally it got resolved; below you can find what I did to resolve it.

1. If you encounter the problem like abve check all the servers have the assembly gaced.
2. If not gac the dlls in all the server and install the assembly in one server (either by deployment wizard or scripts ).
3. Most important thing you shoshould do always is restart the host service for the orchestration in all the servers(Restart the host service that your orchestration belonged)
