I seem frequently getting the following exception in my Solr 4.9 logs, "org.apache.solr.common.SolrException: Invalid chunk header". These exceptions still continue to happen even if I throttle my Solr requests. Does anyone have any suggestions on how to address or work-around his issue?
I have tried multiple configurations (Binary vs XML Communication, HttpSolrServer vs ConcurrentUpdateSolrServer), though when running my test suite it is only a matter of time before this exception is thrown. I found two other threads posted here with what looks like similar issues: * http://lucene.472066.n3.nabble.com/error-message-in-solr-logs-td3999328.html *
