Congratulation pinwc4, you were the first one who got my reward :D. I payout for you already.
Thank you :D

Received and appreciated.  It was quite good luck for me, I had just pointed some workers to your pool about 5 minutes before the block was discovered.

I am running into trouble overnight as well.  I have some workers still going but any that I try to reconnect from fail.  About half of mine failed overnight and they all get errors like this:

Code: [Select]
[16:47:03] HTTP request failed: Recv failure: Connection reset by peer
[16:47:03] json_rpc_call failed, retry after 1 seconds

Since I can not get those to reconnect I am switching them to a different pool for now.  I will leave the working ones alone since they seem to still be submitting work just fine.

Bonus is paid out of my own pocket.

Bonus received.  Your generosity is appreciated.

Thanks

I thought sharing the wallet could be related so I took half the systems and generated new wallets on them.  That did not help any, 1 of them eventually did get a block but that was still way under where it should have been. 

Good to know those statements could be fine, I am just struggling to find a cause.  I did something stupid though, in haste to get this working I deleted most my logs.  I thought I would try starting clean and wiped everything from all the .memorycoin directories and just put the conf and wallet back but did not back them up.  However I did find a couple examples in the remaining ones I did not blitz and they looked very similar, like this:

Hopefully with all that hash we will see a block soon.  Should average about a block an hour based on the coin calculator.  Is that correct?

Anyone tried the Mac version yet, when I get home I will try it and add a few more clients to the pool.

OK, I dug further into more logs on other servers and am seeing more entries of:

ERROR: AcceptBlock() : incorrect proof of work
ERROR: ProcessBlock() : AcceptBlock FAILED

I think this may be related to my problem, any ideas why it would be generating the incorrect proof of work?

MemoryCoin / Linux mining question
« on: December 25, 2013, 09:27:23 pm »
Last week I was mining this coin with no problem, well outside of the Linux crashes.  This week the daemon no longer crashed but I do not seem to be getting any coins at all. 

When looking through the logs the only thing that stands out is an entry like this:
Code: [Select]
ERROR: AcceptBlock() : incorrect proof of work
ERROR: ProcessBlock() : AcceptBlock FAILED

I do not know if that is related to my problem but it looks like a bad thing.

My friend is experiencing the same behavior.  Between us we have 55 systems running, mostly HP or similar servers.  Based on the calculator we should be seeing a block of coins approximately every few hours.  However we have gotten only 2 and they only showed up after some restarts.  Running this for a long time never adds to the balance of the wallet.dat that is shared across the servers.

We are running ubuntu 13.10, though I guess we could rebuild if necessary, I think he pxe boots his servers so it would be quick for him not as quick for me. 

I compiled the source using the following steps:
Code: [Select]
sudo su
apt-get install -y build-essential m4 libssl-dev libdb++-dev libboost-all-dev libminiupnpc-dev git
cd
rm -rf gmp-5.1.3.tar.bz2 gmp-5.1.3
wget http://mirrors.kernel.org/gnu/gmp/gmp-5.1.3.tar.bz2
tar xjvf gmp-5.1.3.tar.bz2
cd gmp-5.1.3
./configure --enable-cxx
make -j8
make install
cd
git clone https://github.com/memorycoin/memorycoin
cd memorycoin/src
cp makefile.unix makefile.my
sed -i -e 's/$(OPENSSL_INCLUDE_PATH))/$(OPENSSL_INCLUDE_PATH) \/usr\/local\/include)/' makefile.my
sed -i -e 's/$(OPENSSL_LIB_PATH))/$(OPENSSL_LIB_PATH) \/usr\/local\/lib)/' makefile.my
sed -i -e 's/$(LDHARDENING) $(LDFLAGS)/$(LDHARDENING) -Wl,-rpath,\/usr\/local\/lib $(LDFLAGS)/' makefile.my
make -f makefile.my -j8
strip bitcoind
mv bitcoind ~/memorycoind
cd
mkdir -p .memorycoin
cd .memorycoin

I then put in a copy of a basic memorycoin.conf file:

Code: [Select]
rpcuser=pinwc4
rpcpassword=x
rpcport=1925
rpcallow=*
server=1
genproclimit=-1
gen=1
addnode=81.17.19.139

Then finally I place a copy of all the other .memorycoin folder files in the directory.  This includes everything so I do not have to resync, and also so I am sharing a wallet.dat file across the machines. 

This process worked fine last week however this week it has not been resulting in any mining.  The CPU usage is high, memory usage is high, I see a HPM figure that looks good on each system, but no coins are found. 

If anyone has any insight I would appreciate it.  This has baffled me for a bit.  With the holidays I have not been able to spend time troubleshooting it but I figure I must be doing something stupid.

Marketplace / WTB 10+ PTS for 50+ MMC
« on: December 20, 2013, 03:23:27 pm »
I am interested in acquiring some PTS.  Unless you are willing to send first I would prefer to go through escrow.  If someone is willing to trade more PTS I would like to get more than 10, just was hoping to be able to get at least 10.

That was embarrassing, my correct address would be MMTkW4RDPqY63D6B9rLXWBQe8KdXKAZf8P

Also it is still running strong, no data corruption and no crashing.  Before I had a cron job to restart every 15 minutes, now it has ran no problem for over 18 hours.

I also found a block with it so I know it is working.

Awesome, it has definitely helped me tremendously.  I have not compiled your latest source that has other changes, I am still just running my modified copy.

But with those 2 simple changes I have been running for over 3 hours at this point with no memory increase beyond what happens in the first few minutes.  I pushed this out to my other machines and they are happy as well. 

Now I just wish it would find another block so I am confident it is working but that is a rare thing to encounter in such a short time.

So far my tests look good.  After a few minutes of running it stabilized around 5752M of VIRT memory usage and after 45+ minutes of running it is still at 5752M.  Whereas before this would have crashed by 25 minutes and I was seeing over 1GB memory increases each minute. 

In fact occasionally I see the memory usage go down for a bit and then go back up to 5752M of memory, so really encouraging. 

Hopefully someone else can confirm that this helps them as well if they were encountering the memory leak.  I had been occasionally running into the corrupt database as well, not sure if this will help with that problem too.

But at least I can run for longer than 25 minutes at a time so I am happier.

Tips are always appreciated

In digging a little further into this I have found I can stop the memory leak, though I do not know if what I did prevents true mining as I have not discovered a block since my testing of the change. 

In momentum.cpp around line 200 where the line "return results;" is I added 2 lines prior.

Code: [Select]
delete aesThreads;
delete sha512Threads;

I now have no memory leak, but wonder if I am still hashing properly.  I would think these lines are not necessary as boost should clean up but doing the above keeps my memory usage stable.  I am showing a good hash/min and CPU usage is high so it is doing something.

Since it looks like the code assumes the threads have completed by that point I think this is a safe operation.  However I am not a programmer so I am really just guessing.

I do not know about others but this did not help me.  The memory leak was much slower, however it was still present when using the -useevp=0 option.

My hash/min went down to about 1/6th what it was before and the speed of the leak slowed down about an equal amount.  This was on Ubuntu 13.10.  So at least for this dist it appears as though EVP is not the source of the leak.
