“连接重置”发生在Solr客户端

Question

当我们调用SOLR服务器时，我们遇到了一个“连接重置”错误。并且我们的并发负载相当小。

以下是SOLR的Tomcat连接器配置：

<Connector port="8983" protocol="HTTP/1.1" 
           connectionTimeout="20000" maxThreads="40000" minSpareThreads="400" maxSpareThreads="5000" maxKeepAliveRequests="100" URIEncoding="UTF-8"
           redirectPort="8943" />

这是我们从SOLR客户端得到的：

Caused by: org.apache.solr.client.solrj.SolrServerException: java.net.SocketException: Connection reset
at org.apache.solr.client.solrj.impl.CommonsHttpSolrServer.request(CommonsHttpSolrServer.java:472)

通过阅读SOLR客户端代码进行故障排除后，我们发现这可能是由于SOLR的Tomcat配置中的连接超时设置不正确造成的。我们决定将其更改为默认值(无限超时)。所以，我的问题是，当将该值设置为infinite时，是否会带来其他性能问题？

调用Solr的客户端是什么？查询结果是什么？不管是什么原因，这个查询是不是一个运行了很长时间而没有返回的查询？
