我的应用开始显示如下错误：

RSolr::RequestError in ProjectsController#index

当我运行 $ rake sunspot:solr:reindex 时，我收到了类似的错误。在我的 ~/log/sunspot-solr-development.log 文件中，我看到以下内容：

SEVERE: REFCOUNT ERROR: unreferenced org.apache.solr.core.SolrCore@78497062 (null) has a reference count of 1

我环顾四周，但找不到解决方案。我在 Mac OS X 上运行 localhost。有什么想法吗？谢谢。

更新：在运行$ rake sunspot:solr:start:https://gist.github.com/1672392 后，我注意到 ~/log/sunspot-solor-development.log 中出现以下错误
