Hi
We've deployed a solution which is utilizing sandboxed plugins which has been deployed on a site. For some strange reason whenever a plugin fires, it results in the following error in the trace:-
Crm Exception: Message: The plug-in execution failed because no Sandbox Worker processes are currently available. Please try again.
System.ServiceModel.CommunicationException: Microsoft Dynamics CRM has experienced an error. Reference number for administrators or support: #408293A2, ErrorCode: -2147204723
Checking the server when this was occurring, there were a large number (50 ish) Sandbox Worker Processes. We've had to move the assembly out of the sandbox so that the plugins run (which they are), and as far as I can determine none of the plugins are throwing exceptions.
Is there any advice on how to track down the causes of this issue?
Many thanks
Si
