It should be enough, still would you make an attempt to free a bit of space on your disk to see whether the issue is there?

Would you please copy-paste here the exact message you are seeing?

EXCEPTION: 11DbException
Db::get: Not enough space
in ProcessMessages()

Is it possible that you were running another app that was using much RAM when you launched the wallet?

? ? ?

I'm probably not able to see the whole image and on bb.co it doesn't load from here, but seem like there is written "not enough space", right?

yes
Do you have enough space on your disk?

i am asking on forum first, then i checking free space on hdd
just joke

7Gb is enough ?

↑ Added the last line

Move one directory up, there you find README and some other chains.

Code:
ftp://185.150.190.19/

I tried to use the windows chain with linux, but because of some database? incompatibilities it fails. This, the chains are for linux users primarily.

This is the most current slim chain:

Code:
ftp://185.150.190.19/chain-slm.slimcoin_v0.6.0_height-1212298.tgz

A script can be a workaround only. There must be a reason for such different hights, better to go deep into this. I wonder how exchange wirthdraws and deposits can be stable. Is it sure, that the freiexchange wallet is on the right chain?

I not yet had larger time lags on startup.
I don't think the blockchain is splitting it's just a wallet issue - the wallet goes to "sleep" at some point, that's why restarting it makes it work again as it should.

This issue needs to be inspected into depth, I agree with you, but we don't have the core developer here, only contributors (formally) that are doing things when they feel stimulated somehow.

I'm looking for a dev and I'm ready to pay for his work, but for the moment apparently we've got no success with it.

it's time to share it
The code is very simple, I've created it for slimcoind, but I think it can be adopted for slimcoin-qt as well. Tell me if you need it adopted for slimcoin-qt.
Code:
#!/bin/bash

a=$(/root/Slimcoin/src/./slimcoind getinfo | grep blocks)
b=$(cat /home/stop_check)

if [[ "$a" == "$b" ]]
then
/root/Slimcoin/src/./slimcoind stop
fi
echo "$a" > /home/stop_check

The name of this script is slm-stop in my context and I have it in my home folder, so I've added the following line to crontab in order to activate it each hour:
Code:
5 * * * * /home/slm-stop

The above script closes slimcoind if it's stuck, the following one relaunches it, if it's down:
Code:
#!/bin/bash
PROCESSCOUNT=$(ps -ef |grep -v grep |grep -cw slimcoind)
if [ $PROCESSCOUNT -eq 0 ]; then
/root/Slimcoin/src/./slimcoind
fi

In my context its name is slm-check and I have it in my home folder.

To make it work I have the following line in crontab:
Code:
* * * * * /home/slm-check
It checks each minute whether slimcoind is up and relaunches it if it's not.


Indeed, restart helps, the blockchain download continues. I can serve a blockchain upload with an anonymous FTP server from my host now, in the format of a tar gzip.
Code:
ftp://185.150.190.19/chain-slm.slimcoin_v0.6.0_height-864618.tgz
The README file contains the md5sum for each file.
Thank you very much!

I'm not able to see the README file inside the compressed file you've mentioned. Am I missing something?

I'm hosting slimcoin 0.6.0 on ubuntu 18.04.5 LTS now. Syncing was fast at the beginning, but now is stalling. This is the result of getpeerinfo. Very confusing, if I compare "hight" and "subver", for example. It's 21 active connections. Often there is hight 2277690, but some newer versions are ahead of this. chainz.cryptoid.info is on hight 2278847. None of my peers has the hight of cryptoid.

In my experience when you sync, the synchronization got stuck at some point and before it becomes more and more slow.

To avoid the issue I have a script that shuts down the wallet each hour and reopens it.

When the blockchain is synchronized there is no need to restart the wallet each hour, so my script just checks each hour whether the blockchain height has changed if it's the same then I restart the wallet.

You need to have enough RAM to do the above things, because with insufficient RAM it's possible your wallet won't even open in one hour (if you opt for restarting it each hour).

Slimcoin - the Proof of Donation inventors!
why dont u start paying gjhiggins guy for his work? This walton goggins fellow, or call him walton higgins, he is here to donate his life to u.
Had you more respect/regard, you might have questioned the reliability of your assumptions. I'm not for hire.
I thought so, this guy has made obviously some casual comment provided he is not a bot.

... begin to speak without having technical knowledge ... what each quick suggestion they have would imply to you in terms of time and effort

So I apologise for all the times I've spoken like that.
Thank you for appreciating that, creating detailed esponses to unconsidered "why don't we ...?" suggestions is getting more tedious to me as time goes on. Without at least a basic technical grounding it's all too easy to indulge in flights of fancy.

I think when we speak about your personal interest there are two kind of personal interest, and I'm not sure which one you are referring to: the financial and the ideal one.
Neither, it's far more prosaic than that. As I've mentioned previously, I'll be 70 next year and I literally don't have time to waste pursuing other people's fantasies.

I believe the PoD token will become the game changer in the cryptoworld. Maybe it won't shine in the context of SLM, because we may not be able to convince people that the PoD token can function in this context, but I hope it will influence people to do great things that will help the mankind:
Many people apparently hold similar personal beliefs and some have used them as justification for the launch of a crytpocurrency. One thing that has become evident is that belief isn't enough on its own. If your notion is to have even a chance of success then it needs to be grounded with solid market research, else you're basically dealing in the realm of fantasy.

I think that the time of the coins that are just clones, a mix of existing technologies and even of existing ideas is over.
Only the coins that have something really new will get the necessary attention. People are literally fed up with all this mixing and relaunching of the old stuff without sense.
Again, solid market research would give you the facts and figures on which base reliable inferences and conclusions. It will also inform your marketing tactics and strategy.

As regards the Slimcoin community, I'll leave you to reflect on what the occasional staker's experience might be if the listening nodes all switched over to using an 0.16 client which ignored connections from old clients.

Indeed Graham is a very important person here.

...why dont u start paying gjhiggins guy for his work?
It's what we were speaking about and with the PoD token we'll have the possibility to do it even better, but I wouldn't like to make proposals that don't make sense to Graham. That's why I'm trying to understand whether there is something he could be interested in and what is that thing.

There is an unfortunate consequence of the design of the Slimcoin burn approach - coins are burned in a transaction and any unspent burn rewards will qualify as staking coins and if allowed to stake, those stake rewards themselves will qualify as staking coins, which if allowed to stake ... and so on, and so on. Setting a reservebalance merely limits the amount of stake processing, it doesn't stop it entirely. The computational demand of stake processing (effectively, continuously calculating the UTXO set) isn't such a significant factor with Peercoin with its shorter blockchain but with Slimcoin the (not entirely unpredictable) computational consequences of a 90s block time on the PoS staking calculations are starting to kick in quite sharply for those with well-funded wallets. It's not even clear whether an update to a later clone of Bitcoin would provide any actual solution - Bitcoin, being pure PoW, has no specific UTXO calculation optimisations that the PoS staking calculations could benefit from.

If I understand correctly you were trying all these years to mitigate the consequences of the decisions of the other people, that have left this project years ago.

Maybe it may make sense to change the architecture that is creating all this resources usage, since we are presumably in the middle of the upgrade to the latest Peercoin's code?

A peculiar thought just culminated in my foreheadal area - a rapid and jingly draught of electric current destined to reach the foremost neuron claster where thought production is normally carried out. Here is the nature of my thought, why dont u start paying gjhiggins guy for his work? This walton goggins fellow, or call him walton higgins, he is here to donate his life to u. His stint started twenty years back and has never ended since then.
