For high throughput indexing, we version updates on the leader and forward onto other replicas w/o strict serialization. If on a leader, an add happened before a DBQ, then on a replica the DBQ is serviced before the add, Solr detects this reordering and fixes it. It's not an error or an indication that anything is wrong (hence the INFO level log message). -Yonik http://lucidworks.com
