repair disk error "unable to bootstrap transaction..."

My iMac was running slow so I rebooted. That still did not seem to help so I did a permission repair which was fine. I then did a Verify Disk which produced several errors and finally said that verifying was stopped and to restart in Recovery Mode and re-run Repair Disk I did that and it said that my hard drive was fine. I confirmed that the volumes matched. After repairing the hard drive from the Recovery Disk I re-ran Repair Disk and I received the same error again. This is the detail of the repair:

The volume 942D6C72-DC32-4171-80E2-C3AFC1D07237 was found corrupt and needs to be repaired.

Error: This disk needs to be repaired using the Recovery HD. Restart your computer, holding down the Command key and the R key until you see the Apple logo. When the OS X Utilities window appears, choose Disk Utility.

I am not seeing any performance issues right now but figure that I should do something about this (I do have time machine running so I am well backed up).

Suggestions?
