I'm using blockchain2graph tool to import the Bitcoin blockchain into Neo4j. It uses JSONRPC calls to read block data. For this, I have to have the bitcoind service running. Is it possible to disable the update of the blockchain while bitcoind is running?

I use the cmdline and I've tried -proxy=127.0.0.1:1234 and -debugexclude=proxy options but it continuously outputs connect() to 127.0.0.1:1234 failed after select(): Connection refused. I don't want this output either.
