Error doing "Process Update" on some dimensions

When processing some of the dimensions in my database using "Process Update" I get an internal error from the OLAP Engine (no specification)... Any known bugs on this, or am I just missing something?

This one is really bugging me Has anyone else had similar experiences?

|||Hy , i have this error too in Sql/olap 2005.|||Having gotten some new information from Microsoft, I am quite certain that this is a bug. Microsoft should be aware of it, and a fix will hopefully make it into SP1.|||

Can you post here bit more information about your situation:

The error description.
What stage it is happening: Beginning, end.
Information about your dimension structure.
Sizes.

Can you try and monitor Analysis Server using SQL Profiler while processing is going, see what is happening before the error occurs
