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.

I am having this exact same issue on Ubuntu 64 (latest version) running in VirtualBox on my MacBook Pro Retina. I have 70GB of SSD and 6GB RAM allocated to the VM. The block chain has simply stopped updating at right around 300,000 block height. What solved this problem for you?
I'm afraid nothing solved the problem for me, I gave it a good go but submitted defeat assuming that the h/ware I was using was too slow. I'll try again though one day when I have spare hardware in the hope that whatever caused it is solved.

I was having the same problem and I even have the same configuration with the MBP Retina.
It has nothing to do with the hardware or virtualization. It has to do with the systemwide file descriptor limits. Linux limits the number of files a process can have open and how many files can be open globally.
While excessively lenient of a policy, applying these settings wiil fix the issue:
sysctl -w fs.file-max=409600
echo "fs.file-max=409600" >> /etc/sysctl.conf
ulimit -n 409600
echo "$USER soft nofile 409600" >> /etc/security/limits.conf
echo "$USER hard nofile 409600" >> /etc/security/limits.conf
