I'm now on my fifth attempt using 2 different servers (one a pretty much clean Debian VM and one an established server).. every time I get nearly to the end of the blockchain sync it just seems to sit around not receiving new blocks and spewing reams of errors such as below. I'm assuming blockchain database corruption but it always seems to be somewhere in the 27#### block range (I've just noticed this). Is this normal? Is there maybe something about this range of blocks, was that when someone was spamming the blockchain? Getting a bit frustrated here sapping so much time and bandwidth and still haven't got a sync'd copy to play with. I don't want to download a torrent copy.
