Looks like:
[2014-02-14 15:01:10,244][WARN ][http.netty ] [elastic1005] Caught exception while handling client http traffic, closing connection [id: 0x55997013, /10.64.32.13:47643 => /10.2.2.30:9200]
org.elasticsearch.common.netty.handler.codec.frame.TooLongFrameException: HTTP content length exceeded 104857600 bytes.
There isn't a work around but if we use a smaller chunk size it'll help. We can further fix it by retrying failed chunks as single units. They made it to Elasticsearch as single units so they should fit.
