Yeah, just comment-out the APRLifecycleListener in conf/server.xml. >> What if you use the NIO connector instead of APR? > > Have always run tomcat with apache and mod_jk has always worked.

The pure-Java blocking I/O connector (BIO) was removed in 8.5.x and 9.0.x, so that's no longer an option. >> Can you post your <Connector> configuration? > > I do not modify anything here. > > My setup: > > workers.properties: > > worker.list=worker1 worker.worker1.type=ajp13 > worker.worker1.host=localhost worker.worker1.port=8009 > worker.worker1.lbfactor=50 worker.worker1.socket_keepalive=1 > > tomcat.conf > > ...

JkMount / worker1 JkMount /* worker1 </VirtualHost> That looks okay to me, though it doesn't look like you actually need httpd in the mix, here. I'll just assume that you are fronting Tomcat for a good reason and not "because that's how it's supposed to be done." > setenv.sh : > > export CATALINA_OPTS="$CATALINA_OPTS -Xms256m" export > CATALINA_OPTS="$CATALINA_OPTS -Xmx768m" Off-topic hint: if you are going to give your JVM 768M, you may as well do it all at once and set -Xms == -Xmx. > export CATALINA_OPTS="$CATALINA_OPTS -Xss256k" > > export CATALINA_OPTS="$CATALINA_OPTS -XX:+UseParallelGC" > > export CATALINA_OPTS="$CATALINA_OPTS -XX:MaxGCPauseMillis=1500" > > export CATALINA_OPTS="$CATALINA_OPTS -XX:GCTimeRatio=9" > > export CATALINA_OPTS="$CATALINA_OPTS -server" > > export CATALINA_OPTS="$CATALINA_OPTS -XX:+DisableExplicitGC" > > > Not sure where these exports came from but they seem to work up to > 8.5.x They control the JVM, not Tomcat. If you are administering this Tomcat instance, I urge you to learn more about what they do.

You aren't using TLS at all, so you can definitely let the APR LifecycleListener go and stop re-compiling libtcnative for each release. It looks like you also aren't using your connector on port 8080, so you can disable that, too. You likely have JVM threads that are sitting idle all the time. Oh, and you're already using NIO. :) > 17-Dec-2016 15:23:08.320 INFO [main] > org.apache.coyote.AbstractProtocol.start Starting ProtocolHandler > [http-nio-8080] 17-Dec-2016 15:23:08.341 INFO [main] > org.apache.coyote.AbstractProtocol.start Starting ProtocolHandler > [ajp-nio-8009] Looks like these guys started-up okay. > 17-Dec-2016 15:23:08.342 INFO [main] > org.apache.catalina.startup.Catalina.start Server startup in 75173 > ms Okay. > 17-Dec-2016 15:59:45.589 INFO [Thread-7] > org.apache.coyote.AbstractProtocol.pause Pausing ProtocolHandler > ["http-nio-8080"] 17-Dec-2016 15:59:45.805 INFO [Thread-7] > org.apache.coyote.AbstractProtocol.pause Pausing ProtocolHandler > ["ajp-nio-8009"] A few minutes later, you stop the server. I don't see any problems, here, except that you are saying you are getting connection failures. After Tomcat is started, can you run this command on the server running both httpd and Tomcat? $ sudo netstat -plan | grep 8009 - -chris -----BEGIN PGP SIGNATURE----- Comment: GPGTools - http://gpgtools.org Comment: Using GnuPG with Thunderbird - http://www.enigmail.net/ iQIcBAEBCAAGBQJYWTvjAAoJEBzwKT+lPKRYTP8P/Rw7FhZ6mQEm8JRibfUdEWA3 qg9gD+2ueIFXkvxfrhIQy1/xfPpmnDIB+X89pSZo+gq9hk9uxPJgneZKGW/K4qD8 sICqi/S6mcEQOGHUYHwdTE9p0lFQwoijZ6O9ViWqcbgTndoYuDCWSNp+3ZMOCeYS IFOZbeUlJyLtMOv1aGnP3LSpi38yHUTLRhBd2/kf5C47+C8iwggN1z6yIRS+vIVb odzI1RR5hPxG4Sy6VNRusiyPowBsMtQ7U0EUdU2abW9X8FD0h8XYx6Qg1NCRUfIU R5OM0SFDu52zbNy1fweZ5P3yW7sOHQ6ocVnrENPoCjJnW05rR8PoGmtKEqDMZJf4 mgbNnB2zb/Eu+RfQaeqjnOB7ch0BxHJE78GfRQSPJ78F+DVHxFCpYNuSA5R+16vE aj/sQMPFf/G2r1GDqgGykxVkkQqBBfPcpGDVbVIHQ2sUiNwW4zya1o3jV2lHNjFd tqnDZg1UWuljBLL/Cm273ueja0t50KCLAr88ZsmFiVCUOktmgjBYzT+pRDCkeLha s8c2Zc1dRr3Qh9ve/LBwVydMO8ZtFw2fGAejSvhhukXbuUNPeMw1PN4pSPRQpgbL NHna5qiziTzXn8yrfJihM2fgontqqP5MtPo0v6JbRhyAcgy8boCz+0llnjxVxBfN eLQxC/coibB4KP0ZhsH5 =LR38 -----END PGP SIGNATURE----- --------------------------------------------------------------------- To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org
