Running: Ubuntu Trusty 14.0.4 LTS 64 Bit mod_jk/1.2.37 Apache/2.4.7 (Ubuntu)
Hello, I have much investigated into this, but have no idea, why the AJP connections from the Apache (MPM worker) to the AJP backends pile up. They do not get closed, they stay in state ESTABLISHED. Over night, the idle connections should be closed from the pool, but the do not get closed, they get more and more every day, and the RAM of the Apache server gets eaten up. We have the following /etc/libapache2-mod-jk/workers.properties: --- # not used workers.tomcat_home=/usr/share/tomcat6 # not used workers.java_home=/usr/lib/jvm/default-java ps=/ # General worker template worker.template_01.type=ajp13 worker.template_01.socket_connect_timeout=3000 worker.template_01.ping_mode=A worker.template_01.connection_pool_timeout=600 worker.template_01.connection_pool_minsize=1 worker.template_01.socket_keepalive=true worker.template_01.reply_timeout=1800000 --- and on the AJP backends (Jboss / EAP), we have also set the connectionTimeout to 600000 ms , as written in https://tomcat.apache.org/connectors-doc/common_howto/timeouts.html But even a Backend with low traffic, (maybe one request per minute) gets 300 established AJP connections after some days. Here the content of /etc/apache2/mods-enabled/jk.conf: <IfModule jk_module> JkWorkersFile /etc/libapache2-mod-jk/workers.properties JkLogFile /var/log/apache2/mod_jk.log JkLogLevel info JkShmFile /var/log/apache2/jk-runtime-status JkWatchdogInterval 60 </IfModule> It looks like the JkWatchdog is not running? Or do the connections do not idle because of some non-Apache requests like cping/cpong? Your support is much appreciated.
