Assume also that the package contains more than one concurrent XML tasks that consume the same XSLT style sheet. When you run the package, you receive the following error message:
[XML Task] Error: An error occurred with the following error message: "The process cannot access the file '<File Path>' because it is being used by another process."

Note This issue also occurs in SQL Server 2012.

Status
