Help: Geth has peers but it's not syncing.

Hi guys,

I'm having issues to finish downloading the blockchain. I'm currently executing geth with

geth --cache=1024 --jitvm console

Originally it was downloading fine (slow, but fine) but some hours ago it stopped syncing at all.

> net.listening
true
> net.peerCount
20
> eth.syncing
false
> admin.chainSyncStatus
undefined
> eth.blockNumber
1124996

As you can see, I have network connectivity and peers, I'm still some months behind on the blockchain, and geth is not syncing. I'm running Ubuntu 16.04. Any idea what's going on?
