我们在生产中遇到了无法调试的 Solr 行为。首先是solr的配置：

Solr 版本: 6.5 , Master with 1 Slave 与下面提到的配置相同。

JVM 配置：

     -Xms2048m
     -Xmx4096m
     -XX:+ParallelRefProcEnabled
     -XX:+UseCMSInitiatingOccupancyOnly
     -XX:CMSInitiatingOccupancyFraction=50

其余均为默认值。

索尔配置：

    <autoCommit>
      <!-- Auto hard commit in 5 minutes -->
      <maxTime>{solr.autoCommit.maxTime:300000}</maxTime>
      <openSearcher>false</openSearcher>
    </autoCommit>
    <autoSoftCommit>
    <!-- Auto soft commit in 15 minutes -->
      <maxTime>{solr.autoSoftCommit.maxTime:900000}</maxTime>
    </autoSoftCommit>
    </updateHandler>

    <query>
      <maxBooleanClauses>1024</maxBooleanClauses>
      <filterCache class="solr.FastLRUCache" size="8192" initialSize="8192" autowarmCount="0" />
      <queryResultCache class="solr.LRUCache" size="8192" initialSize="4096" autowarmCount="0" />
      <documentCache class="solr.LRUCache" size="12288" initialSize="12288" autowarmCount="0" />
      <cache name="perSegFilter" class="solr.search.LRUCache" size="10" initialSize="0" autowarmCount="10" regenerator="solr.NoOpRegenerator" />
      <enableLazyFieldLoading>true</enableLazyFieldLoading>
      <queryResultWindowSize>20</queryResultWindowSize>
      <queryResultMaxDocsCached>${solr.query.max.docs:40}
      </queryResultMaxDocsCached>
      <useColdSearcher>false</useColdSearcher>
      <maxWarmingSearchers>2</maxWarmingSearchers>
    </query> …
