The bounty have not been claimed yet.
Still looking for a solution(!)

A few people over at our IRC-channel is working HARD to figure out the problem.

I think a packet sniffer would also tell us the answer to this, and wouldn't require a restart of anything?

We tcpdumped all bitcoind->pushpoold comminucation and founded 4 duplicate getwork's.
What we should do about it, or why it's that way - we don't know.

Where the hell is your IRC channel?  I've been lurking in what I thought was the channel all day and haven't seen a peep.

I'm chasing a hunch. If anyone currently using bitcoins.lc would like to compare results from disabling Long Polling vs. leaving LP on, I'd find it instructive.

We finally solved our issue with rejected shares!
Credits to ius over at #bitcoins.lc for helping us out.

His account was just credited with 10 BTC ($270)
Thanks all for trying to help us! We really appreciate it!

If any other pool operator want to know what it is, please contact me and we can work something out...

I'm planning to keep that to me self, due to i think the other pools based on pushpoold will eventually face the same problem.
This issue costed the pool/me personally 10 BTC + a whole day of hard work with debugging, tcpdump and ~10 people that tried in all ways to help us.

If I'm about to release this, the pool need something in return.
We'll see if this is just an isolated issue with our pool, or if anyone else will face the same problem.

If there's a bug with pushpool (which is what it sounded like from IRC) then you should let it be known. The developer of that was good enough to let you use it freely... share the love.

edit: Also it'll save me a weekend of serious debugging. If I track it down myself I won't be keeping secrets!

+1

If it's about pushpool, then you should tell them.

pushpool is released under GNU Public License version 2 (LICENSE)

Pretty sure this means if you make modifications to the code (especially for money), you are in breach of this unless you release these modifications to the community (but I'm not a lawyer, might be wrong!)

If you want to recoup the 10BTC 'cost' of fixing, then I would set up a new bitcoin address for donations related to this specific bugfix, once you reach 10BTC and bitcoins.lc have made the money back for the original payment to ius, then split the rest between bitcoins.lc and ius.

...on another note: bitcoins.lc seems to be fully up again.  I would say that having approx an hour downtime since I started mining there on Tuesday seems pretty good, otherwise it's been totally stable - keep up the good work Jine!

No, GPL forces you to release the source code only if you release a modified version of the software.

The GPL puts you under no obligation to release source code you have changed, it only forbids him from redistributing it without the source code or from trying to sell the product at all; offering a bounty to fix an issue with the code is perfectly fine as far as the GPL is concerned and so long as he doesn't attempt to sell the fix to other pool owners he is perfectly fine.

Just to make things clear:

I'm not selling the fix, but other pool operators may contact me and we can negotiate something so both parts are happy.
AFAIK that's okey with the license to.

That sounds pretty contradictory.

I wonder how would, say, the linux project ends if anyone that spots and correct a bug would ask something to release the patch.
