2 disconnects in less the 30 seconds... New coins are doing something to the pool I guess... Please do something...

Are you using bfgminer? If so, what version? Do you get the same disconnects on cgminer? I'm running USB ASIC on cgminer with no disconnects.

No it is 3.x cgminer problem again. I have 3.1.1 and 3.3.1. It was OK for a while but now they are back... And only on your pool...

Can you provide me with logs? Preferably protocol dumps (-P I think) around the time a disconnect occurs.

[doublec]

I use 3.3.0 with no problem. I'll try the latest version 3.3.3.

[Lucko]

That figures now we have fast blocks... When I can't mine hire...

Just one fast block though... we had two 18 hour rounds before that...And this one will probably end up being just as long. Don't be upset just yet

[bitpop]

Its weird i0coin is only 6. Also p2pool mm miners are considered solo miners.

[Apheration]

What do you mean it's only 6?

[bitpop]

6 i0coins per block

[Apheration]

oh

[doublec]

Its weird i0coin is only 6. Also p2pool mm miners are considered solo miners.

It started at 48 IIRC. It's halved a few times since then.

[Lucko]

Any news on disconnects?

Since I don't get the anser I did this little test:

They don't like disconnects... FPGA is downclocking and ACIS are crashing...

I would really like to use this pool but I can't till this gets fixed... This is happening only hire...

[doublec]

I'm not getting them. Is anyone else getting disconnects?

[Lucko]

Yeah I am getting those disconnects pretty frequently too actually.   I thought it was just my wifi.

I know that he has this problem too...

I can give you access to this miner if that will help. But for some resone I can't run -D

[doublec]

If you can solve the -D/-P problem and get logs it will be helpful otherwise there's not much I can do.

It looks like CGminer bug. I use cgminer-nogpu and it crashes... And I tested on 3.1.1 and 3.3.1. But to get any help from CGminer team is from my experience mission impossible...

EDIT: I did that on 3 different computer so I don't think it is anything wrong with all of them...

"-D -P" works for me on cgminer v3.3.1 on 64bit Linux. Maybe it's a Windows thing. I'll continue to look into the disconnect issue but it's difficult without being able to reproduce.

Is it normal that I can't run debug on windows 7 x64?

If I use -D or --debug cgminer crashes. And -P doesn't do anything...I tested this on 3.1.1 and 3.3.1.

Normal? No

Happens? Yes

Bug? Yes

Known cause? No

Fix in the works? See Known cause above.

30+ hour rounds  

@doublec - What is the reason the gap for when you stop mining and your expected payout starts to decline is so short? It seems almost instant. Every once and a while I have computer/block erupter trouble that I usually fix within 10 minutes or so but by that time I notice I already have started to lose estimated payout (and much faster than at the rate it took to "charge up").
