When creating a new replica from another server on a Domino 8.0.1 (64 Bit) on Windows 2003 (64 Bit), the server crashes and you will find these lines in your NSD file:

This seems to be similar to SPR RMAA7D9HAP. The Knowledgebase says that this will be fixed in 8.0.2.
I informed IBM and they promised to provide a hotfix to solve this issue.

Update: Received hotfix today. Problem solved!
