Topic: Cant synch (Read 1051 times)

No, you cannot do that or you will end up reindexing the whole database. The post that told you to do that was deleted for spamming and being outrageously incorrect and bad advice.

Resyncing the entire blockchain usually fixes the problem. It isn't pointless, it makes sure that you have a non-corrupted copy of the blockchain. You can't just use the data you already have if it is corrupted.

I deleted it but it didn't help. So i deleted two files and all blockchain started to reindex. And now it got stuck a lot earlier
Am i really the only person with such problem?
I'm thinking about posting it as a bug.
Synching for me really seems impossible.

Can i delete last block?
Downloading all from 0 again seems rather pointless.

I checked antivir logs, it has no detections.

It seems to have helped. Now just 36 weeks left but error again:

2017-07-24 17:58:10 Error reading from database: Database corrupted

I've run memtest - no errors. As i wrote before, im doing regular backups with CRC checks and no errors too.

What next?

I'd be inclined to agree that the root cause is your RAM... Little "random" errors like this are generally caused by faulty RAM.

I'd highly recommend you download and run memtest86... if you have a faulty stick of RAM, Memtes86 will find it

Have you redownloaded the entire blockchain from scratch (i.e. deleted the blocks folder in the datadir or used a completely new datadir)? If not, try doing that.

Otherwise, you may have a hardware issue, not necessarily disk. More likely you have a problem with your RAM. Just run system diagnostics and see if it finds anything wrong with your system.

It's not out of space issue.  And i use latest version of bitcoin-qt.
I'm using my comp for mining, gaming, making backup and CRC check, downloading torrents - all work fine.
I've read that this issue can be caused by bad disk, so i tried it on different disks.
The only thing that comes to my mind is internet connection or network card. But torrents work fine, my internet connection is great, and i dont use wifi, proxies, vpn etc.
I can connect some usb wifi but does it make sense?

I've tried to resync or reindex several times for few days. With 200mbps and NVMe disk it's couple of hours before failure.

For me its obvious that if bad block is downloaded it should be deleted and re-downloaded automatically.

What can i do??

Firstly, make sure you are using the most recent version of Bitcoin qt available(0.14.2, second make sure you have enough hard drive space( im not sure of the current size, I think 150-175gb).

Ive searched up your issue and it seems it might be an issue with corrupted blocks were downloaded, its suggested that you either do reindex, or delete all your blk data and re download the blockhain.


If the above doesn't work then you might have a hardware issue. Ill do so more research, get back to me once you've tried the above and you have the results.

For few days im trying to synch bitcoin-qt. It all the time either crashes or hangs.
Ive made several tries so far and the best result was 45%.
Current errors:
