7X + 1Y = 12 just doesn't work when X and Y have to be whole numbers because they are the number of lines in the log for each error.
And no one cal tell me how they found 12 lines with errors in the log when there were only 8 records that had errors:
* 7 errors of one type
* 1 error of another
Sure, if Y=5, and X=1, then it works, but the equation doesn't balance if no one knows what X and Y are.

So how's your day going?
