Did you see my reply on the dev list, sent before I told you that your question belonged on this list? In that reply I told you that replicationFactor will have no effect after you create your collection. It also cannot cause problems with the write.lock file. I also said this: There are three major reasons for a problem with write.lock. 1) Solr is crashing and leaving the write.lock file behind. 2) You are trying to share an index directory between more than one core or Solr instance. 3) You are trying to run with your index data on a network filesystem like NFS.
