I have a rMBP running dp6, it was all fine until last week that I noticed that mdworker is taking up 100% cpu power and ran for days on end. Using the power indicator, it says it is spotlight that is using significant power. so I used the fs_usage with sudo to see what files it is indexing. But it seems to me the file accessing is not as intensive as the power drain suggests, and even after putting those folder into the exclusion list in the spotlight menu, the power drain persists... rebuilding spotlight index doesn't help, either. So does anyone have a clue what is going on here? Thanks!
