我们在调用 SOLR 服务器时遇到“连接重置”错误。而且我们的并发负载很小。
这是 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 客户那里得到的:

通过阅读 SOLR 客户端代码排除故障后，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所致。我们决定将其更改为默认值(无限超时)。所以，我的问题是，将此值设置为无穷大是否会带来其他性能问题？
最佳答案
调用 Solr 的客户端是什么？并提出查询？出于某种原因，查询是否运行了很长时间而没有返回？
关于java - "Connection Reset"发生在 Solr 客户端，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/5725329/
