Title: No Block Source Avaliable - Bitcoin-QT Post by: jackg on December 29, 2015, 12:02:31 AM I get an error on bitcoin core whenever I load it. It says: No Block Source Avaliable.
I have full connection to all 8 nodes at a pinging speed of less than 20ms for each node. Any suggestions? (NOTE: not sure if I have already posted this so please tell me if I have!)

Supposedly that has worked for people before to clear this problem. Can you also post your Debug log before reindexing?

I have not done much downloading of that and am still 2 years and 53 weeks behind! I will check the debug log first. And post any relavent information here. Title: Re: No Block Source Avaliable - Bitcoin-QT Post by: Jet Cash on December 29, 2015, 05:02:15 PM Sounds as if you just need to wait. Go by the green bar, and not the catchup time. About half of the chain was created in the last year.
If you are in Somerset, England, I can give you a copy of the blockchain on a USB stick. :) Title: Re: No Block Source Avaliable - Bitcoin-QT Post by: achow101 on December 29, 2015, 05:08:13 PM What is reindexing?

Depending on what OS you are using, you will need to change the start command to include the -reindex flag so that it will reindex the blockchain on start. All this does is deletes all of the databases and then rebuilds them with the downloaded blocks.Title: Re: No Block Source Avaliable - Bitcoin-QT Post by: jackg on December 29, 2015, 05:20:08 PM Sounds as if you just need to wait.

Can you suggest the reindexing command? I am loading back up bitcoin-qt, it will take a while.

Bitcoin core is part of the bitcoin network so it is accepting and relaying transactions to other nodes whenever it is open. Some, like the ones above, were non-standard and that is being reported.

It is now running OK, I think. I will post here if I get any problems. Thanks for the help. Title: Re: No Block Source Avaliable - Bitcoin-QT Post by: jackg on December 29, 2015, 06:08:37 PM It is working fine now. Thank you for your support and suggestions.
I have updated its priority on taskmgr.exe to high. Title: Re: No Block Source Avaliable - Bitcoin-QT Post by: shorena on December 29, 2015, 09:37:36 PM It is working fine now.

My fan got too warm. Also, it slowed down the display of my computer and since then, Norton Internet Security has flagged up an error saying it is using high sis usage. However, I assume this is normal! Title: Re: No Block Source Avaliable - Bitcoin-QT Post by: shorena on December 29, 2015, 11:01:35 PM It is working fine now.

High CPU usage durring sync is normal. If your system overheats because of that you might want to look into that though. If its an older system it might be just dust clogging the air circulation.

If its an older system it might be just dust clogging the air circulation. It is fine. I would expect this from a computer that is around 6 years old. It has been underclocked for its entire use, so that keeps its CPU very well. When new, it was at 2.3GHz dual core - 4.6GHz! As soon as I changed the priority it stopped overheatng. I would also expect for it to go at least 50 megabytes per hour. I think that tht is a reasonable assumption for it.

Considering that the blockchain (blocks folder only) currently uses 57.4GB I hope you can do more than 50 MB per hour or it would take you > 40 days to fully sync.

It will slow down a bit for the last year, but it should not take longer than 2-3 days total. |
