Would it be possible to send the scene to support at chaosgroup.com so we could investigate further? When you do please make sure to mention this thread and the V-Ray version that you are using.

When you get to it please send it over. It will be difficult to troubleshoot the issue without it.

You can look for smoothing group issues, coplanar faces - the usual suspects when dealing with booleans. Could also be a GI issue when you're using low IR settings.

1st thing to do after a boolean is check the smoothing groups

You render with IrrMap ? if so, I'd go for unsufficient IrrMap sampling. In such cases, I usually uncheck Use IrrMap option in the problematic objects' material settings.
