Capitalizing the first letter of the username fixed it, now it can connect!
Interesting, as the view-your-balances link doesn't care about capitalization at all.

Phoenix isn't very happy and doesn't seem to be delivering work very well, but I suspect that is an issue at my end.

Thanks for the help!

I'm working on improving the stale count and delivery of work so hopefully this will improve from the pool end soon.

I've added the ability to include a devcoin address when registering. Devcoin merge mining turns on at block 25,000 (currently it's at block 23,874). I don't know if I'll enable it on the pool yet, but if I do and you want devcoins you can re-register and include a devcoin address. Note that bitcoin addresses are valid devcoin addresses so for all existing registered users I can set the devcoin address to their bitcoin address. Then if you want to claim your share you can import the private key from bitcoin into devcoin.

At this stage I'm thinking of enabling merge mining for devcoin, and monitor the effect. If it causes an increase in stales or other issues I'll disable it until my work on reducing pool stales is done then re-enable it.

ixcoin has reached block 45,000 and mmpool is now merge mining ixcoins along with bitcoin, namecoin and i0coin.

Very impressive, and extremely low stales. Nice job doublec! Thanks.

last hrs i had a very high stale-rate at the mmpool: ~ 12 % and rising
 
in the beginning it was only: ~ 1 %

12 % is too much, if there is no improvement, i have to change the pool

last hrs i had a very high stale-rate at the mmpool: ~ 12 % and rising

What miner (and version of that miner) are you using? I was running another process on the pool server for a while which impacted performance quite a bit until I noticed and killed it. This may be a reason for increasing stales today.

KIV's GUI-miner/W7-64 OpenCL - with this miner i had max. 1 % stales, at some pools near to 0 %

Edit: version 2011-07-01

Edit2: let's have a look after the stale-rate from now on

I also have much stales

shares: 3906
Stales: 468

When ixcoin was added the stales were increasing

two hrs later: stales < 1 %

it's fine again

what ever you did doublec,
it worked !!

till today i had about 15%+ stales

since restart of my miner today cause i finaly added ixcoin, i have done >300 shares with 0 stales !!!

great work, thank you!

I've made some changes to the pool backend to try and improve getwork throughput when longpolling is informing users of a found block. Previously the pool would slow down as it suffered a 'thundering herd' of users asking for work for a few seconds. Hopefully this impact is reduced now. If you see any problems post here, PM or email. If you've been getting messages from your miner about the pool not being able to provide work fast enough I'd be interested in knowing if the frequency of this has reduced or increased.

i found little bug on pool:
1. Did 0.67 BTC withdraw - finished with http 502 error. Pool web was unaccesible few minutes.
2. After few minutes web was accessable again. BTC balance was still 0.67 BTC, so did another BTC withdraw. Result was the same as before.
3. After few minutes web was accessable again and BTC balance was again 0.67 BTC.
4. So i looked into blockchain and found out that both 0.67 BTC transactions were sent - and later really arrived into my wallet.

DoubleC - i own you 1.34 BTC. Sent me address to send to.

Seems like a nice 51% double spend attack on the pool. LOL.

The 502 was because of crashes happening due to issues with the new backend. I've hopefully stomped on all them now. You can keep the 1.34 BTC as reward for testing

Any plans to MM the following :

BTC
NMC
IXC
I0C
DVC



What other pools are doing MM with the 4 coins ? I think Eligius is also MM BTC, NMC, IXC and I0C ?

Thanks !

I'm currently MMing BTC, NMC, IXC and I0C. DVC isn't merge mineable yet but I'm planning to enable it when it is to see how it goes. You'll have to ask Eligius what exactly they're merge mining.

Exactly.  I mine on Eligius and I'm pretty sure they are only paying out Bitcoins and Namecoins right now.  If they are merged mining I0coins & Ixcoins, they aren't paying them out yet.

But I may need to go coin sign a Ixcoin & I0coin address to my bitcoin address to get payouts or something.  I haven't been following them as much, b/c doublec's is the best at the moment.

Does anyone recall Eligius's payout system and/or fees?  I believe they were established as a proportional payout with zero fees, but lately I've been thinking they are pay per share potentially with fees.  Please advise if you happen to have time to research.

Thanks!

Hey DubC, are you going to re-open the Bitparking Ix/I0 exchanges?

[doublec]

I've added the ability to have a Coiled Coin address when registering. Those that register with this new coin can start receiving them when/if the pool starts merge mining them.
