Look at the Workers->Shift Graph
The light red shading is the 5Nd+ of the last reward

So now that you took the time to make that nice shading you need to add to your "to do" list to make it unshade for orphans and stale blocks Tongue

Also now that I see it, eventually it will all be shaded except for the leading edge so maybe each block should get a different color?

So, we just got a share that would of found us a block, but it was stale. The tooltip says "Share was submitted 1 minute too late." Does this mean the miner submitted too late to the pool late, or did we simply legit lost the propagation race?

The miner should never have been working on the stale work in the first place. The pool had informed all miners of the block change and the need to change work 69 seconds earlier. Older mining hardware/software is probably the reason - bear in mind this doesn't mean this miner is getting paid for stale work as his rejects are higher and they're not paid for.

Thank you very much for the explanation. I get it now. It is unfortunate that this may happen because a miner's software did not react properly to the job change notification.

Being one of our (new(?)) biggest miners here at Kano's C/K Pool, i hope jbravo will fix anything there is to fix, if there is something to fix and if it was simply just not a fluke.

@Kano i see your reply just now. Thank you for the in depth log. Not changing job 1 min after a job change seem like the miner would be wasting a lot of shares.

It wasn't an orphan after all, it was a stale share.

He submitted it 69 seconds late to kano.is Tongue

ckpool has (as yet before never tested) code to try submit stale block shares anyway ... just in case.

kano.is put out our 388788 block change to F2Pool's block on time:
[2015-12-17 11:38:04.925] Block hash changed to 00000000000000000497f638fc378166d2d14742d4b77187209fe5f32a57afe3

poolbench also shows they saw it 573ms later:
stratum.kano.is:3333 2015-12-16 19:38:05.498000

But the share came in 69 seconds later:
[2015-12-17 11:39:13.492] Possible block solve diff 182123374943.539276 !

[2015-12-17 11:39:13.604] Submitted, but rejected block 388788

So yeah there was no chance in hell of it ever being a block Sad

Edit: oh also CKDB's report on it (including my manual interventions 'Orphan' and 'Unworthy')

Woo hoo, I'm not old, but close. My first "PC" was a 486 computer that had the sweet "turbo" button, 512mb hard drive. Installed a 14.4k modem and voila the WWW. Cool

Before that I had vic20, commodore 128, etc.

Mine was a chisel and stone beat that!

I remember growing up my dad chatting on packet radio. Was a 9600 baud modem connected to ham radio He ran the local 146.820 repeater. You could chat with an apple 2 e and this modem to anyone within range of the repeater. That was back in the early 80s

This block 388788 is showing up as an F2Pool block on the Blockchain... Angry

Yeah just doing an analysis of what happened.
They mined 2 blocks quickly and thus orphaned ours.
More info later once I work out the timings.

I discussed this case in a different post months ago, but when your pool gets a block then your pool is the first one to start on the next block and if you get lucky and that next block is ultra low diff then you will likely get it before the rest of the miners start mining it, guess it a 100-200ms advantage.

Turns out it was nothing like that. The share from the miner was just a very stale share. Had it come 2 minutes earlier it would have been a block but it was over a minute late. The miner has some very old hardware in his mix so it's possible the device in question was very bad at working on fresh work.
