I resolved this issue by following actions.
Check point 1. Apache proxy
If you are using Apache proxy, you should check if you change the setting like below. That is clearly saying you use proxy internally.
| Code Block | ||||
|---|---|---|---|---|
| ||||
<Server port="8000" shutdown="SHUTDOWN" debug="0">
<Service name="Tomcat-Standalone">
<Connector port="8090" connectionTimeout="20000" redirectPort="8443"
maxThreads="48" minSpareThreads="10"
enableLookups="false" acceptCount="10" debug="0" URIEncoding="UTF-8"
protocol="org.apache.coyote.http11.Http11NioProtocol"
scheme="http" proxyName="your_domain.com" proxyPort="80"/>
<Engine name="Standalone" defaultHost="localhost" debug="0">
<Host name="localhost" debug="0" appBase="webapps" unpackWARs="true" autoDeploy="false" startStopThreads="4">
<Context path="" docBase="../confluence" debug="0" reloadable="false" useHttpOnly="true">
<!-- Logging configuration for Confluence is specified in confluence/WEB-INF/classes/log4j.properties -->
<Manager pathname=""/>
<Valve className="org.apache.catalina.valves.StuckThreadDetectionValve" threshold="60"/>
</Context>
<Context path="${confluence.context.path}/synchrony-proxy" docBase="../synchrony-proxy" debug="0"
reloadable="false" useHttpOnly="true">
<Valve className="org.apache.catalina.valves.StuckThreadDetectionValve" threshold="60"/>
</Context>
</Host>
</Engine>
</Service>
</Server> |
Check point 2. Modifying /etc/security/limits.conf in my CentOS 7 server.

* hard nofile 500000 * soft nofile 500000 root hard nofile 500000 root soft nofile 500000 |
Check point 3. Modifying a value of maxThreads.Connector in <confluence_home_directory>/conf/server.xml
You may able to see maxThread as a member of <Connector>. The default value of maxThreads is 48 - I just modified it to 4096

Once your modification is done, you should restart your server to take effect.
Check point 4. Modifying
...
setenv.sh
One of the possibility is caused by memory limits. In my case, mx used the default value (1024m), so I changed its size to 2048m.
