[matiu]

I will sumit a patch for this today. In the mean time you can erase the contents of db/ and try again. Thanks. —

Hi @cryptogenesis

Sorry, the error was not related o the previous comments, I check the code and it is ok.
Further examination of the log you summited, make me realize that your file:

 /root/.bitcoin/blocks/blk00000.dat

seems to be empty. (no sync progress is reported while processing that file, which is not possible).

Could you check bitcoind to be sure that bitcoind has finished downloading the blockchain?

[cryptogenesis]

Hi @matiu,

Thank you for the help -- my Bitcoind is up to date, see:

root@xxxx: bitcoind getmininginfo
{
"blocks" : 291320,
"currentblocksize" : 0,
"currentblocktx" : 0,
"difficulty" : 4250217919.86953545,
"errors" : "",
"generate" : false,
"genproclimit" : -1,
"hashespersec" : 0,
"pooledtx" : 188,
"testnet" : false
}

I have a symbolic link from /root/.bitcoin to another disk drive, could that be interfering?

Also: -rw------- 1 root root 134217728 Jan 25 09:46 blk00000.dat

[cmgustavo]

how do you have your configuration of bitcoind.conf?
Maybe you forgot txindex=1

[cryptogenesis]

Hi @cmgustavo,

Bitcoin.conf:

rpcuser=XXX
rpcpassword=YYY
server=1
maxconnections=100
rpcssl=1
rpcallowip=X.X.X.X
txindex=1

[matiu]

if you tail bitcoind log, everything looks normal, and progress is 1.000 ?

Hi @matiu , everything looks great in the bitcoind log

Copied my bitcoin folder to a new Ubuntu instance, still getting the same issue:

[matiu]

Thanks. Coud you share blk000001 and blk000002  so we can try to reproduce the error?—

Roads? Where we're going, we don't need roads!

[matiu]

Also, please check if the last version fixes the issues, some changes were made in the synchronization process.

[cryptogenesis]

@matiu apologies for the delay -- I updated to latest version of insight, still got the error, I have uploaded blk00000.dat here:

http://cryptogenesis.com/blk00000.tgz

blk00001.dat can be found in:
http://cryptogenesis.com/blocks.tgz

[cryptogenesis]

Let me know if you need any other blk files

[matiu]

Hi @cryptogenesis. Sorry the delay.

I tried your file blk00000.tgz.
It is almost empty, that is why you were having problem. If you do

xxd blk00000.dat

on the extracted file you will see that there is only some info that the beginning (the genesis block), but nothing else.
