我的Solr系统（Solr版本3.6.1）有两个核心。当我在专用的Solr服务器上调用以下命令行以添加文件然后为文件建立索引时：

java -Durl=http://solrprod:8080/solr/original/update -jar /home/solr/solr3/biomina/solr/post.jar /home/solr/tmp/2008/c2m-dump-01.noDEID_clean.xml

我在/usr/share/tomcat7/logs/solr.2013-12-11.log文件中得到一个异常（等待大约6分钟后）：

SEVERE: org.apache.lucene.store.LockObtainFailedException: Lock obtain timed out: NativeFSLock@/home/solr/solr3/biomina/solr/original/data/index/write.lock

（您可以在此消息的末尾看到它的详细输出）。

我试图修改锁的超时时间（通过将设置writeLockTimeout为300000），但这并不能解决问题。我没有使用任何自定义脚本，而只是post.jar使用Solr
3.1.6附带的脚本来添加和编制索引。

关于什么需要更改才能消除此错误并将成功的XML文件添加到Solr并为其编制索引的任何想法？

solrconfig.xml的相关部分（对于名为的内核original）：

<indexConfig>
    <!-- maxFieldLength specifies max number of *tokens* indexed per 
field. Default: 10000 -->
    <!-- <maxFieldLength>10000</maxFieldLength>  -->
    <!-- Maximum time to wait for a write lock (ms) for an IndexWriter.

    <writeLockTimeout>300000</writeLockTimeout>

solrconfig.xml的相关部分（对于名为的内核deidentified）：

<indexConfig>
    <!-- maxFieldLength specifies max number of *tokens* indexed per
