[1423GH] ABCPool PPS - Proxy Pool For High & Steady Mining Rewards

[MintCondition]

All of a sudden I'm only making Rejected "Stale" shares.. What's going on?

This was due to the maintenance that we were performing, and should have last +-30 minutes. Stale/invalid counts should now be incrementing normally.

abcpool.co is now supported on miningmonitor.com!

[bal3wolf]

Did you lower the price per share and the stales have went up alot from me getting like 20-30k with only 1 stale to now 1 every 100 shares almost.

[Jezzz]

It's unfortunate that the stale rate is so high.  You should get with the developers of cgminer and the other unsupported clients and attempt to work out the issues. 

I see rfcpool.com is re-opened.  Spose I'll go there until the issues are fixed.  Hard to beat 0% PPS though.  Please keep us posted on your progress.

[MintCondition]

Did you lower the price per share (...)

We still have 0% fee. Since difficulty went down last week, the price per share has been raised to 0.0000276900796620 at that moment.

(...) and the stales have went up alot from me getting like 20-30k with only 1 stale to now 1 every 100 shares almost.

If you were actively mining on august 20 or august 21, your reported shares may be out of sync with your balance. See my earlier posts for more about this issue.

We are constantly monitoring the servers to try to get the highest valid percentage possible. Over the past four hours the pool has rewarded 99.45% of incoming shares.

If your stale rate stays high there may be something wrong with your setup.

We're sorry to see you go! ..but did you know: Your miners were last seen mining two days ago. The changes made less than 24 hours ago have drastically improved the valid and stale rates for many users.

Over the last 14 hours, cgminer 1.5.8 users have obtained a very low 0.48% invalid rate. However, previous versions of cgminer are currently the worst performing of all clients on ABCPool with 1.5-2.0% invalids.

Overall invalid rate is only 0.55%.

UPDATE 00:15 UTC: RPC server has been restored to service. We introduced changes to the RPC server that should make it more compatible with the original pushpoold. Since most clients play nice with pushpoold, these changes to ABCPool should benefit compatibility with mining clients.

MintCondition,

I've been mining the whole day with latest DiabloMiner, it works ok now.

There is a little issue still open, though, that is the LP socket being closed often (every two minutes now).

Code:

[8/24/11 11:51:00 PM] ERROR: Cannot connect to pool.abcpool.co: Bitcoin disconnected during response: 200 ok

I still think the LP socket should not be closed so often, anyway it does not seem to be causing problems to DiabloMiner apart from this warning message.

Best regards.

NEWS: ABCPool was offline for several minutes, and is now operating normally again.

[spiccioli]

MintCondition,

this morning I woke up and I found out that rejected shares are now around 4-5%.

I'm using phoenix and DiabloMiner, both show the same amount of rejected shares.

Is there something going wrong?

spiccioli.

[nomnomnom]

I am also seeing a higher reject rate at the moment:
[1288 Accepted] [56 Rejected]

Some rejects look like this:
[26/08/2011 12:46:48] Result 000000002a369ade... rejected  
[26/08/2011 12:46:52] Reject reason: ['unknown-work']

what does unknown work mean, never seen that before  

Edit: I am using phoenix 1.62 if this matters somehow

[spiccioli]

MintCondition,

another issue (so to speak) is that, it seems to me, if I do an instant cash out it does not subtract the donation that is set inside My Account->Account Details.

Is this by design or am I wrong?

Cheers.

We're experiencing some growing pains. We will focus on minimizing stale and invalid shares in the coming days. Until levels are back to normal we have closed registration.

what does unknown work mean, never seen that before  

The unknown-work error code means that the work you are submitting has either never been handed out to that specific worker, or that the work was expired because it is older than 120 seconds. This error should only occur for workers below 100Mh/s, and when we restart our backends for updates (ca. two times daily).

(...) if I do an instant cash out it does not subtract the donation that is set inside My Account->Account Details.

This is by design. Your donation is already being subtracted from the PPS amount each time we process incoming shares. Since last week we've been keeping track of those donations, and we plan on displaying them in your stats.

Oh, and have we thanked you yet for your donations? Thanks!

Hey guys, great pool!  I've been with this pool for just about a week now and I'm very happy with the results.  Make sure you guys list your site on btcmerchants.com the free bitcoin merchant directory. Thanks, and keep up the great work!

[xzion]

seems like a great pool Mint, very secure for the miners. But what about you?
How does the pool cope with a 8-10mill share round, where you've got to pay out 4-5 times more than you're earning?

No-one likes to see too many 10mill share rounds, that's for sure. In the long run however, they are offset by those 100k rounds. Our buffer protects us from streaks of bad luck.

NB: please don't double-post. Use either this thread, or our newbie discussion thread.

Hey MintCondition , something is seriously wrong with your pool, it was running fine
the last few hours, but now its producing rejects like crazy

Hi nomnomnom,

We indeed has some problems from 18:02 UTC to 18:21 UTC. At this moment ABCPool is operating normally again; we are investigating the cause. The rejected shares are not influencing the result of our miners.

[Chlorine]

One may have noticed that I am not the regular author of ABCPool forum posts. Normally I am working behind the scenes. As the pool grows and grows, MintCondition has asked me to be his first backup. For our miners nothing will change.

Happy mining!

[Chlorine]

UPDATE: Further investigation showed us that during the last two days a higher than expected amount of stales shares has been occurred.

We have taken countermeasures to prevent this in the feature. These stale shares will not affect the results of our miners in any way.

[Lord F(r)og]

hmmm, stales were about 1.5% until your investigation but for now it's close to nuthing. good work for you.
