On Version 7.2 in Test:

User ran REBUILD_INDEXES then experienced this problem when running the Analytical Engine.

The following was seen in the Engine log screen:

The User then bounced the server and re-ran the Engine.
This time the Engine hung and never completed.

The User discovered the following when running rebuild_indexes again:

"Some indexes or index [sub]partitions of table MSDEM.XXXX_XXXXX have been marked unusable
Thu Feb 4 11:06:46 2010"

This is seen multiple times with each line referencing a different index.
