I also saw this message today when trying to run the Recompile HAL Files maintenance, when a report was running. It didn't log me out, but I had to wait until the report had finished before it let me recompile.
I would like to know what BackgroundHALShouldPause does, and how to use it. While it's listed in the HAL Primitives report, it is not used in source code and it doesn't appear in the LMS HAL...
