[yhaenggi]

Im running abe (darkgamex.ch:2751) with bitcoind testnet3 and i have this error since some time:

The problematic block is 265322 (it fetched upto 265321).

I would like to see the raw block. Can you run this command and post the resulting b265322.dat file?

dd if=/home/k1773r/.bitcoin/testnet3/blocks/blk00008.dat bs=1 count=2000 skip=55889898 of=b265322.dat

I may need you to increase count=2000 if the block is large.

[yhaenggi]

ive done it with count=10^6, as a block can be max 1MB to save some time if needed.

[jtobey]

The block has an unusual version number, and Abe interprets bit 8 of it as a Namecoin merge mining flag. This is fixed in the latest code, but for your version this might work:

ignore-bit8-chains = ["Bitcoin", "Testnet", "Testnet3"]

(replace "Testnet3" with whatever you named the chain.)

Thanks, the hotfix works.
