Hello, I'm operating some services under this environment.
1. server
OS : RHEL 6.x
JVM : 1.8.0_x
WEB : httpd 2.2.24
WAS : tomcat-8.0.44(tomcat-native1.2.14)
2. server
OS : RHEL 6.x
JVM : 1.8.0_x
WEB : httpd 2.2.24
WAS : tomcat-7.0.75(tomcat-native1.2.14)
<!-- Define an AJP 1.3 Connector on port 8009 -->
<Connector port="8009" protocol="AJP/1.3" redirectPort="9443"
URIEncoding="UTF-8"
acceptCount="200" acceptorThreadCount="2" maxThreads="300"
minSpareThreads="50" *connectionTimeout="15000*"/>
I can see a RUNNABLE thread in my tomcat8.0.44 server that waits keep
alive timeout(connectionTimeout) status.
