The updated version of the Revit Server stability Hotfix has been released, and is available for download here:
This Hotfix addresses a crash that may occur when Revit is uploading data to Revit Server during a Synchronize with Central operation.
The Hotfix must be applied to both Revit Server and the Revit product to be effective. Instructions on how to do so can be found in the Readme.
Please also note that you need to have Update Release 2 installed for your Revit product (build number 20110916_2132).
Thanks for your patience while we worked on getting the files updated!
