It looks to me like the memory leak in ppcoind is related to the number of blocks created/mined. My pool now has a low number of blocks produced, due to lower hash rate and the larger number of proof of stake blocks produced by others. This has resulted in needing to restart the daemon less often to reclaim memory.

I wonder if proof of stake miners are seeing a memory leak. Is anyone running a node 24x7 for proof of stake producing a reasonable number of blocks per day seeing this?

I haven't observed memory leak on any of my nodes that are generating stakes, whether production or testnet.

Last I gathered from the forum it seems related to either 1) mining pool 2) services with large number of connections. So far it still evades me how to reproduce the issue despite of some attempts.

I restricted my pool to a small number of connections for a couple of weeks and it made no noticeable difference to the memory consumption so I think (2) is out. Are you keeping a cache of blocks or anything like that when a block is found via getwork?

It's probably some early investors lose interest or feel uncertain about the 0.3 protocol upgrade.
Not saying that you do it deliberately, but the "uncertainty" is a bit manufactured.

The getwork block cache is actually existing bitcoin code and I didn't modify it. The cache is cleared every time a new best block is received on the block chain. I have looked at this code before and didn't find anything suspicious.

Code:
        if (pindexPrev != pindexBest ||
            (nTransactionsUpdated != nTransactionsUpdatedLast && GetTime() - nStart > 60))
        {
            if (pindexPrev != pindexBest)
            {
                // Deallocate old blocks since they're obsolete now
                mapNewBlock.clear();
                BOOST_FOREACH(CBlock* pblock, vNewBlock)
                    delete pblock;
                vNewBlock.clear();
            }

Well you are entitled to your opinion. I can only say that I believe I am doing the best work I can, in the most professional and responsible fashion in my opinion. And I am proud of the work I produced so far.

Somehow I feel that you have developed animosity toward me and ppcoin project, I honestly don't know what warranted it as I think I have always treated you professionally and with courtesy. As I have said before, why can't people here tolerate petty differences and be united in the cause of liberty? I hope in the future you would have more constructive contributions to ppcoin.

Best Regards,

Please don't confuse lack of politeness with animosity. I think you did the community a great service by implementing POS and showing ways to do it. By openly criticizing you for the few things which go wrong, I give you a chance to explain to the community why you do things a certain way. You may feel a bit judged - but so do politicians in every functioning democratic society - so you're in good company. And yes - as a cryptocurrency developer you are a public figure.

There is always a lack of transparent communication it seems on this forum and far too many Trollers and haters here, I think that it is hard to avoid feeling directly targeted when people point out flaws in code or ideas or implementation of such code or ideas especially if they coming from all angles and sources.... Not having a go at anyone in particular just saying that discussion is good and healthy and the fact that Sunny King is very active in posting on here is a true credit to himself and his project.... not one other coin do I see weekly updates for and this makes it nice to see a timeline of the dev process and general fairing of the PPC project.

I also think that Jutarul raises a number of good points and has asked really important questions in the past and we need more clever and interested and productive people like you in the community...

I'll finish on saying that I would vote for both of you in the next election should u decide to run... much better choice than Obama or the current coalition government we have here in the UK!! so get ur applications in... maybe u could run together then I wouldn't have to make a hard choice on my vote Smiley anyways keep up the good work

He needed something to use to symbolize it, better than using things like religion saying that Sunny is the Jesus of PPC.

Search for Sunny Jesus result:  Tongue



Stupid jokes aside, what are the plans in PPC future developments?
Sunny is publishing a nice log in https://bitcointalk.org/index.php?topic=114994.0;all
 
But what about us, the users?  Roll Eyes
Can we get a bit more organized and start thinking about useful features that are not just eye candy crapp but something that actually adds value to PPC as a method of transferring value from point A to B and without the need for five nuclear power plants?

 If you feel like, you can not come up with anything, think about stuff you dislike about BTC (bloated dat files, killing of small independent miners), VIsa, Mastercard, Dwolla, PayPal etc... and how to turn those nasty "features" to PPC advantages etc. Smiley

While reading what I wrote, use the most friendliest and relaxing voice in your head.
BTW, Things in BTC bubble universes are getting ugly....

The gui build in the link is done by xchrix I believe. gui build is not yet officially supported in release due to the complexity of bitcoin's verifiable build system (gitian-builder) that we use and also due to our limited resources. But there is a possibility that an unpolished gui build would be included in the coming 0.3 release (no guarantee though).

Usually that means the built-in cpu mining is turned on (especially if you have multi-core processor). Have you check the 'gen' configuration parameter in your ppcoin.conf file? Note the default is turned off, so if you don't see 'gen' in the configuration file then cpu mining should be turned off.

Our seed nodes would be offline some time next week due to hosting problem. While I look for alternatives, I might need your help to volunteer a temporary seed node.

This means, any node running ppcoind as server (if you have >8 connections then you are definitely running as server). Then I would point seed.ppcoin.net to it's IP (of course static IP is better, but even dynamic IP is ok, as long as it doesn't change very often). Please only volunteer if you can run the node 24x7 for at least one month.

The job of seed node is to help new node with initial download of block chain. The load on seed node is very low I believe so bandwidth shouldn't be a concern.

Let me know if you want to volunteer. Please PM me static/DHCP, IP address and upload bandwidth if residential line. Any recommendation of BTC hosting providers is also appreciated. Thanks!

2+ million coins mined early, yesterday little over 9k ... you really think that most people are dumb enough to buy PPC even at 0.00013 rate?



Coinotron under 10 Ghashes, BitParking under 5 Ghashes, Vircurex reports network hashrate around 135 Ghashes. That is so cool, few people
have the most old and new coins, and have enough stake to do whatever they want to, including limitless free double-spends attempts.

PPCoin is early-adopter scam coin, nothing more.

Apparently, you know nothing about PPC.  Way to go.
