[jira] [Updated] (HTTPCORE-421) RouteSpecificPool timeout Occuring processing HTTP request while using NIO

     [ https://issues.apache.org/jira/browse/HTTPCORE-421?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Venkata Satya Teja Siram updated HTTPCORE-421:
----------------------------------------------
    Description: 
Hi Team,
We have a an application in which we are making an asynchronous request to get the response.For making asynchronous Request we are using apache nio

Reference link followed:
https://hc.apache.org/httpcomponents-core-ga/tutorial/html/nio.html

While using this we are facing an issue.The issue is also not always simulatable.I was not able to figure out the root* cause.

The issue details are as follows:
java.net.ConnectException: null
        at org.apache.http.nio.pool.RouteSpecificPool.timeout(RouteSpecificPool.java:170) [httpcore-nio-4.4.4.jar:4.4.4]
        at org.apache.http.nio.pool.AbstractNIOConnPool.requestTimeout(AbstractNIOConnPool.java:560) [httpcore-nio-4.4.4.jar:4.4.4]
        at org.apache.http.nio.pool.AbstractNIOConnPool$InternalSessionRequestCallback.timeout(AbstractNIOConnPool.java:821) [httpcore-nio-4.4.4.jar:4.4.4]
        at org.apache.http.impl.nio.reactor.SessionRequestImpl.timeout(SessionRequestImpl.java:182) [httpcore-nio-4.4.4.jar:4.4.4]
        at org.apache.http.


Version being used:

<dependency>
			<groupId>org.apache.httpcomponents</groupId>
			<artifactId>httpclient</artifactId>
			<version>4.5.1</version>
		</dependency>


		<dependency>
			<groupId>org.apache.httpcomponents</groupId>
			<artifactId>httpcore-nio</artifactId>
			<version>4.4.4</version>
		</dependency>


Initially i thought issue was with pool and increased pool size(NIO Pool) while load testing. But some times it occurs if a send single request only although pool size is 1000 ,the issue is occurring.

Is this issue has something related to cpu core size, on 4 core processor its happening very less and on single core processor it occurs very frequency
is more..For NIO reactor , we have given the default config.As the documentation specifies the number of dispatcher threads would be dependent on number of cores on the system.

Any help regarding this issue?
