Errors with Grant permission on an item: HRESULT: 0x80004004

Apr 5, 2011 at 10:43 AM

Hi,

We have a list with single item permissions managed by a workflow with the Custom Workflow Activity "Grant permission on an item". Whenever users are editing multiple items at the same time (Datasheet / Excel) around 20-30% of the workflows are not successful and remain in an error state (Error Occured / Failed on Start).

We can reproduce this error and get the following Error in the Log:

Operation Aborted (Exception from HRESULT: 0x80004004 (E_ABORT)) System.Runtime.InteropServices.ComException [....] at Microsoft.SharePoint.Library.SPRequestInternalClass

It looks like there is a problem with multithreading and parallel execution of this workflow activity. Is there a workaround or solution available for this problem?

kind regards,

till
