SharePoint 2013 / Access Services 2010 AfterUpdate Data Macro

Hello,

I have an Access 2010 Database published to a SharePoint 2013 site. There is an AfterUpdate Macro that runs successfully once, then errors until Access on the client is restarted. I am able to reproduce the problem by creating a new Access database with two tables and a simple AfterUpdate macro on Table1 that inserts a record in Table2. An AfterCreate Macro exhibits the same problem.

The error in Access is "The Microsoft access database engine encountered an error while communicating with SharePoint. The server was too busy to complete your operation."

The only error on the SharePoint farm is in the trace logs when verbose logging is turned on: UpdateListsImpl.UpdateLists: Update 14 is cancelled due to time out.

I've adjusted the settings in the Central Admin for Access Services 2010 to their max with no change.
