I've got SocketException(Connection reset) frequently. This is occurred during distibuted search and logged like below in request server. At First, I thought that the reason of exception is long gc pause time of jvm. So I changed connectionTimeout of the connector in tomcat server.xml to 60000ms. However, In gc pause time under 10000ms that exception still occurs. Does this exception not caused by gc pause? Requested server is not closed and just sometimes occures stop the world by gc. What's the reason and how can I solve this?
