Can't get my participation node to sync with the blockchain

It seems like my node has caught up substantially but I’m not sure why. One minute the last committed block was 61 and the next minute it jumped to ~20,000. Now it seems to be up to ~82,477 committed blocks; definitely isn’t happening at a consistent rate.

Anyway, here’s the output of “cat node.log | tail”:
