I would like to understand or do my best helping you to understand this issue.

I got the following (shortened) logs:

I don't understand what the three in parentheses values are exactly. I guess the last number is the count and the middle one is the number of increments, is that true ? What is the first string (identical in all the errors) ?

How can the last number (assuming it's the count) be negative knowing that I only sum positive numbers ?

An other point is that the highest value seems to be *always* the good one (assuming this time that the middle number is the number of increments).

I'll try to make myself clear:

I count events and accrued incomes or a costs attached to the events.

In the following line I'm sure that I'm summing cost

(03a227f0-a5c3-11e1-0000-b7f5e49dceff, 28, 588000) and (03a227f0-a5c3-11e1-0000-b7f5e49dceff, 28, 294000) 

588000/28 = 21000 && 294000/28 = 10500. These are euros stored multiplying them by 100000. So I get 0,21 euros int he first case and 0,105 euros in the second case as unitary price. We never put 3 decimals in our prices and we do have a lot of products that cost 0.21, which makes me think that the first value, the highest out of the two, is the correct one.

In the following line I guess that I'm summing events (one by one so)

(03a227f0-a5c3-11e1-0000-b7f5e49dceff, 19, -3) and (03a227f0-a5c3-11e1-0000-b7f5e49dceff, 19, 19) 

So obviously, if all my assumptions are right, the good value is again the highest. And I don't get how the count could possibly be "-3".

So the highest value would be always the highest one making your fix efficient (in my cas at least). 

I hope this could be useful to Sylvain Lebresne or anyone working on this bug.
