nutch readdb统计信息，域统计信息和solr记录不匹配

如何解决nutch readdb统计信息，域统计信息和solr记录不匹配

我已经抓取了2个深度为3的网址。 solr中的记录数是142。 域统计是 173烤 第363章 165 fronteracashandloan.com 8 gangnamsushihouse.com

readdb统计信息是 状态1（db_unfetched）：246 状态2（db_fetched）：153 状态3（db_gone）：4 状态5（db_redir_perm）：32 状态6（db_notmodified）：20 状态7（db_duplicate）：81

请问是什么问题。

   overriden by a Crawl-Delay from a robots.txt and is used ONLY if
   fetcher.threads.per.queue is set to 1.

  <value>0.5</value>
  <description>The minimum number of seconds the fetcher will delay between

 If the Crawl-Delay in robots.txt is set to greater than this value (in

 If set to -1 the fetcher will never skip such pages and will wait the
 amount of time retrieved from robots.txt Crawl-Delay,however long that
 might be.
