Pay per share has its ups and downs, just not as drastic as score and proportional. I made more in 12 hours on deepbit doing pps with my 68Mh/s a few days ago than i have in 2x as much time on either slush or eligius.

Well, don't take it personally, but my previous post was exactly about people like you Wink.

Heh, I'm not taking anything personally. I don't want to see pps on your pool, and you're pool is my pool of preference. I'm also a complete and total newb to the scene, but I'm picking it up fairly decently.

Side note, good work and thanks for getting things back up and running and really smooth so quickly since getting back from holiday. As soon as I actually turn over enough for a payout there's definitely a donation coming your way from me.

In fact, I started with repair immediately when I came home; I still had jacket and shoes when pool started to work again Smiley

BTCDig - mining pool

What happen?
On Saturday's evening (UTC), bitcoin daemons on two independent pool servers ate all available memory (RAM & swap) and fall to massive I/O operations, which make servers extremely slow. Central server switched traffic to the last machine, but this machine was unable to handle all traffic and some RPC calls started to timeout. Then those miners getting RPC timeouts probably started to ask server even more frequently (miners don't implement any "polite waiting" in the code and send new RPC call immediately after error/timeout). Those thousands of requests per second were the last piece to shut down last working machine Smiley.

Time for implement this (polite waiting) in miners?

Yes, it would be very nice from miner developers...

Is it a known bug in the bitcoin daemon that initiated the failure cascade?

Or is it untraceable? Would be good to get some development work done on that too, no?

Initial problem was that bitcoind ate few GB of memory. It was first time I've seen that and cannot tell if it is bug or some kind of P2P attack as mentioned in my previous post.

cdhowie started implementing a nice proxy that would switch pools should it become unreachable: http://bitcointalk.org/index.php?topic=5506.0;all
We are also working on exponential backoff, so that the pools wouldn't get hammered all the time, until miners start implementing these features themselves this might be an option for serious miners Cheesy

Lesson learn
a) Don't take holiday Smiley
b) If I'll take holiday, don't tell it anybody Wink.
c) Try to setup watchdog restarting bitcoind when it started to use too much memory.


Man, option a) Is fucking sad! Don't do that.

Maybe a small business partner or other worker to watch over pool when you are off-line?

A nice script that sends you SMS with current memory usage will do the job. Hard one is to find a working connection in some mountain regions Grin

I'm certainly not complaining but what's happening here I haven't seen payouts like this since difficulty was in the 72k range

The pool's size is down considerably, so you're taking a much larger share of each block.. It's also taking longer to solve a block, obviously, but that looks pretty good to me Smiley

But if all are mining for current block only means then how can other pools solving blocks?
I think a bug is there, which instead of current block also counting the shares of all the blocks which got solved for the past 4 hours.
Seems locked somewhere which is still trying to solve one particular block while other pools solves blocks.

In deepbit many blocks solved.

The "bug" is called Variance.
