Hi Ajit,

also it is rather late I think I ran into the same issue today.

I had an Agent that was triggered from view with a selected document. It is written in Java and does something before it tries to embedded some files from local drive. When that embed operation starts it client throws same Java messages according concurrent use of database handles.

The reason is (I think) a problem with handling of documents addressed through getDocumentContext().

How did I fix it:

My intention was to get the selected document. So I switched from getDocumentContext() to agentContext.getUnprocessedDocuments() and processed just first document (if any) in collection.

That works just fine without any error.

Hope that helps,

Mike
