Ok I think I have done it!  I have fixed the issues where we where getting...

Code:
2011-09-06 18:01:24: Listener for "coinserver1 test": 06/09/2011 18:01:24, Problems communicating with bitcoin RPC 0 2
2011-09-06 18:02:09: Listener for "coinserver3 test": 06/09/2011 18:02:09, Problems communicating with bitcoin RPC 0 2
2011-09-06 18:02:20: Listener for "coinserver1 test": 06/09/2011 18:02:20, Problems communicating with bitcoin RPC 0 2
2011-09-06 18:03:05: Listener for "coinserver3 test": 06/09/2011 18:03:05, Problems communicating with bitcoin RPC 0 2
2011-09-06 18:03:16: Listener for "coinserver1 test": 06/09/2011 18:03:16, Problems communicating with bitcoin RPC 0 2
2011-09-06 18:04:01: Listener for "coinserver3 test": 06/09/2011 18:04:01, Problems communicating with bitcoin RPC 0 2
2011-09-06 18:04:57: Listener for "coinserver3 test": 06/09/2011 18:04:57, Problems communicating with bitcoin RPC 0 2
2011-09-06 18:05:07: Listener for "coinserver1 test": 06/09/2011 18:05:07, Problems communicating with bitcoin RPC 0 2
2011-09-06 18:05:53: Listener for "coinserver3 test": 06/09/2011 18:05:53, Problems communicating with bitcoin RPC 0 2

Restart your miner and see if you get that error.

Now on to rejected shares caused by unknown-work reason!

I think I will add a dashboard feature that breaks down the rejected shares. Something like this...

Code:
stale   |duplicate    |unknown-user    |unknown-work   |time-invalid   |
5       |1            |11              |152            |1              |
------------------------------------------------------------------------
 

The issue with this is that bad users will have a chance to see more data to hack the system.  Ah well maybe I'll disable it after the fix is done?

Hey Davinci,

I just restarted my miners, will give you an update in about 2 hours to see if all the RPC connection errors have gone

I think it would be productive to see what kind of stales/rejects we get

If you only show the breakdown on the Dashboard page (make an overall total per user) then no one can/wants to do any damage

Might be an idea ?

Looks like you are getting closer to launch !

Great job !

Cool!

Update your profile to add www.nmcbit.com so that your user bar is correct.

I did a quick thing to see how many "unknow-work" people are getting if you click on your stales % on your dashboard you will get a page that has the total unknown-work.

Can anyone let me know how much you have and for a few of your workers?

Let me know for example on of my workers has
6,165 shares and 51 Unknown-work

You do not need to give me the worker name.

If you are getting a lot focus your miners on one of the 3 servers starting at coinserver1.nmcbit.com.

4629 shares/ 51 unknown
4329 shares/ 39 unknown
4422 shares/ 51 unknown
4979 shares/ 51 unknown

Odd that 3 of them have the same amount of unknowns. They were all on the same server (nmcbit.com), I've just now rotated them across the coinservers, leaving the one that had 39 on nmcbit

I have a Rejected shares issue work around...

The issue shows up if you are using cgminer and can be reduced if you change your scan time to 15 seconds or less.

Code:
cgminer -o http://nmcbit.com:8332 -u username -p password -d 0 --no-longpoll -s 15

I know for sure that poclbm works fine with my pool.

I'm going to move on to supporting merged mining since its only 300 blocks away and the main reason I started with namecoins.

Yes, on to merged mining please.. Smiley

Can a change to the best-chain criteria protect against 51% to 90+% attacks without a hard fork?

Awesome news!
Found software that will fix the problem for cgminer and others that get "unknown-work"!

http://manpages.ubuntu.com/manpages/hardy/man1/balance.1.html

Key part to read is...

A "%" instead of a "!" as a group separator declares the previous group
       to  be  of  type  "hash".   This  means  that  instead of a round-robin
       algorithm, a hash distribution based on the client ip address  is  used
       to determine the destination channel. This allows connecting one client
       always to the same server (e.g. balancing http  sessions  to  a  single
       server).


It was built for bitcoin before bitcoin!  lol Cheesy

It's late I have not implemented it yet but I will tomorrow.

YES! I am so happy!  

This is so cool as it completes the last of the miner side issues other than "not providing work fast enough" but that's caused by the cron job and non-clustered DB!
Right now I have namecoin and pushpool clusted I just add servers as needed, and the web site clustered.  Once the SQL is clustered man! I will just need to add servers as more people come!  ZERO down time for miners once SQL is clustered.  WELL actually I do need to work on DOS attacks!


Example of the "not providing work fast enough" problem...

Due to the possibly upcoming attack of BitcoinEXpress ( http://bit.ly/poTuzs ) nmcbit will not pay out NMC for your safety.

1. All your namecoins are safe No one can take them from you!
2. NMCBIT will still pay you for invalid blocks caused by the attack I will take the loss!

The issue is with spending while there is an attach since a block chain has "who has what namecoins"  if someone creates one chain where you got paid the second chain could created by the attacker can erase your payment after it's been made.  However your coins would not be lost as the alternative chain would have the coins before you made the payment.


In short your coins are safe the issue is spending them you will need to wait 120 blocks before you accept any payment of NMC as valid.  Finally the reason I stopped payments is because an attach where my payment to you was voided would mess up my database and create a lot of extra work I don't need right now.

Some time before the end of the week I will be 0.00003030 BITCOINS per share (minus 3% fee) as an option instead of namecoins.  You will be able to do ether or but in both cases we will only be mining the namecoin network in an effort to protect it.  I will keep the NMC if you opt for bitcoins.  Please let everyone know once I have set it up to pay out BTC it will be announced here and on my front page.

For as long as I can do so I have thousands of BTC, tones of silver and lots of gold so I can afford it but the issue is will it be worth it?  Ether way I will pay for as promiced.

NOTE:  Please do not assume I will pay BTC right now, I am still working on it.  

Regards

It's ready!

I pay just under 20% more than what deepbit will pay help save Namecoins!

Just click PPS check box beside your worker and BOOM you are getting paid btc I keep the NMC however you can get proportional namecoins if you like.

Your shares are updated once a NMC block is found so the more blocks we find the faster you BTC end up in your wallet.

It will hold!  I have been working on it for a long tim also I have upgraded the SQL server to Large and if I have to I will upgrade the rest.  I wanted to see if I could do this with Micro servers that's why my pool was struggling and I wanted to make major changes so a small pool was good enough until I was happy with it.

But I have no choice now.

Is that 10btc bounty still up for Gh/s being pointed that way? It's past the posted September 5th date, but still on the post and no list of how many claimed it? Right now I'm mining like 70:30 Deepbit:NMCBit split of power. Have about 1.25GH.
