From what I understand what you are saying it that reset doesn't happens for everyone at the same time. I think it dose. And it happens when total score gets to big. The error accrue during reset because some other system is imputing new share that was found.
Why is the total score not in double integer? Or a byte integer what is increase every time when score is reset, then when block found is divided from user score?!
Sorry I can't figure out what you are asking?

EDIT:
Still problems with these blocks (what red color has)

Did you increase you hash rate? If so to can you give me a number on what it was and what it is.

When reset accusers some workers don't get reseted. I guess it has something to do with time the share is submitted and calculated during reset(score=score+share*value)
If this is what is happening, then all that is needed is a mutex_lock/unlock around the score update/reset functions, which is an easy fix. Another option is to trigger second reset if some of the miners has 50+% from total score, which is a workaround, but might be easier to implement depending on the pool structure.
I doubt Slush wouldn't have fixed something simple like this until now, but he is busy with other things lately, so it is possible that he have just missed it.
My personal guess is that it is probably time/clock based and some of the backends is not reset, because it's time is off - that would also explain the situation with the total score not being reset few times too.

I looked at logs(from api on my account) from the time I was figuring out is it me or is it the pool and I was once on wining side of the error. At time of the reset only one of my miners got reseted and other had about the same score. My estimated reword jumped to over 3 BTC, but the round finished and blocked was recalculated... So I'm sure that workers don't get reseted but not sure what is the reason... But I think it is a valid guess...

EDIT: And fixing the bug is easy finding it is not. Sometimes you need another set of eyes.

You would have to ask the programmer. Most likely there is not a "type" that is large enough to handle the number we are dealing with. We can't say for sure what is happening, we can only take a WAG(Wild Ass Guess) based on what we are seeing. No one but Slush can answer your question and he is Missing I Action at the moment.

Getting so close to a score reset again... I don't want it to, after last times screw up. Please find a block in the next 5 minutes or so!

Have I said something wonderful or witty? It's unlikely, but if so all donations:

I usually get around 0.028 BTC per block - these two blocks are clearly wrong:

Did you increase you hash rate? If so to can you give me a number on what it was and what it is.
We have there 2 PC's, every PC has one GPU. #1 with 300 mhps #2 with 200 mhps. All PC's are 10-20% in use (movie watch, any game playing) in a 24h day, but they dont run the whole day.
I work for 2 pools, one pps and the Slush pool for testing. I use cgminer with balance pool method.
My avarage hash rate on slush pool is ~240 mhps from  2013-05-30 14:27.
I work for the slush pool without any cheating, i dont have the block red colored (on the list) who i have changed the systems. I have only colored what i was on the whole block online, and the hash rate was fix, but i was punished with lower reward what did not deserve it.
I dont have "mining rig" what only run miner the whole 24h day. I have personal computers what when they online then work for the pools.
/sorry for bad grammar, i speak whole better in German and Hungarian language/

**EDIT**
The my account page says:
Average hashrate in last 10 rounds: 351 Mhash/s

I think we agree? cool!
From what I understand what you are saying it that reset doesn't happens for everyone at the same time. I think it dose. And it happens when total score gets to big. The error accrue during reset because some other system is imputing new share that was found.
Why is the total score not in double integer? Or a byte integer what is increase every time when score is reset, then when block found is divided from user score?!

You would have to ask the programmer. Most likely there is not a "type" that is large enough to handle the number we are dealing with. We can't say for sure what is happening, we can only take a WAG(Wild Ass Guess) based on what we are seeing. No one but Slush can answer your question and he is Missing I Action at the moment.
Why not? double integer has 18446744073709600000 max volume. Thats not enough?
But when not enough then the optimal solution would a extra byte.
When the current TOTAL SCORE variable is full, then we have to do only increase a variable (declare name with= "spin") with 1.
So when the duration is on 1:00:00 then we reset the Total Score variable (we dont reset the user score variable!) and we set the "spin" to 1
on 2:00:00 we reseting again, and set the spin to 2
on 3:00:00 to 3 and so follow..
and when the block founded, then we calculate from these method:
reward = ( user score / spin ) / total score * 25
All is done?!

This will lead to wrong results: on spin 1 the total score is 1234567890, but on next spin it is 1934567890 - they are never equal

How are u calculated this? On the spin increment the total score reset it to 0.

I mean just before it is reset, because it based on time and not some value it will always be different, so ... wrong end results
The numbers are just for example

The numbers are just for example
score = score + exp(round_time/C)
The result is only a number ^^
With these method, when the round time too long is, then the value would overflow.

Exactly and you should reset the score for all miners at specific time, because the total score is a sum of all the miner's scores

The "reset" just normalises all the scores. No information is lost. If no "reset" happened, you'd receive the same score and the same reward.

I see, but u should understand, when u reseting all scores, then we lost information.
That means when the all score is reset at 1:00:00 then its all newly, what i have shared before i would that lose. Because i would have then 0 score.
The users score should NOT be reseted!

Or maybe you didn't understand?

Then, i think i dont understand.
For me says reset thah reseting scores to zero.
