Maybe. Long poll is also feeding miners empty blocks, so that could also be the reason. But those are not allowed to rollntime, so we are talking a very small amount of work. The chance to produce a block from this is very low.

Why use empty blocks for long poll? Because you can produce this work already before the block change. This way all miners are informed of the block change very quickly, which results in less rejected work.

I was thinking, why aren't pool operators announcing LP is being retired and force ppl to upgrade? Even GBT is better than LP.

Can you explain it, please? What is so wrong with old versions?

Old cgminer/bfgminer have a bug that suddenly make them request work from the server over and over as fast as they can. This amounts to a DDoS attack which can be quite heavy for the server. Giving those miners work that is as cheap as possible to produce is one of the many changes I made to keep things running smoothly even with those miners sometimes going nuts.

That's mean dynasty have old, obsolete cgminer version and that's why we generated empty, useless block?

Last block mined has 0 TX in. Something might be wrong.

Just some miners still on ancient cgminer versions. Those blocks are already rare and will be rarer as more people upgrade their miners. I send a message to upgrade whenever those miners get a reject, but I guess most miners aren't watching their logs that much.

any plans on making fastest user list longer?

There are no plans for that. And I think top 50 is as much as makes sense to display at one time.

But perhaps it could have multiple pages, like the block list.

when I joined, the pool was 200ghash and I was ~2,5ghash and made it to top 25 that time, now pool is 10x faster and I'm only 2x faster and cant even fit to top 50 Tongue

Have you considered something like CloudFlare to help protect the front end? It won't do anything for the mining ports, but it might help defend the website.

In this instance it was a pool server bug undetected in testing that made the getwork miners go nuts. But yeah, I have considered CloudFlare. I may go for that in the future with more servers.

Sorry for the web server barely being able to move. There's a DDoS attack in progress. Sad

Just a thought. I mention CloudFlare specifically because it's free. $$

Looks like bfgminer now is working onstratum. I see less shares acceptedon my console but the hashrate on bitminter looks right. Is this the way its supposed to work.

Yeah, that's because of variable difficulty. When it says "Accepted f7564e7c Diff 16/4 GPU 0" that means this proof of work would be good enough when mining even at difficulty 16, but you are currently mining at difficulty 4. On the server this will count the same as 4 difficulty 1 proofs of work. So you will see the accepted count on the server go up by 4.

Is merged mining still occurring with stratum?

Yes, merged mining happens whether you use stratum, gbt or getwork.

Great! Gives you an edge over other pools.

Apologies for the bumpy ride.

Technical mumblings: There was an issue with longpoll (both getwork and gbt) because of a race condition. Seems it never triggered before I switched to a different java virtual machine. And of course it never triggered during testing, even with that JVM. Have to love those bugs that only occur in production.

I believe that issue should now be resolved.

Bad news is, I didn't know bfgminer requires mining.get_transactions to be implemented. Edit: it doesn't, actually.

So bfgminer is still acting up. But any miners running getwork or gbt should be fine again.

Working on the bfgminer issue.

I know other pools have dropped namecoin with stratum (btcguild and ozcoin for example).

Seems a change on the server is causing miners to sometimes run crazy. Working on it.

Doc,
Are you restarting pool? A lot of rejects and 503 open id login error?

PS: I just saw your post..Is DoS affecting mining or just web is attacked?
