Hello, I am currently running tomcat 8.0.32 and have tried to upgrade to 8.5.8 and 8.5.9 without success. I use mod_jk to connect apache to tomcat running on centos 5.11 with Apache 2.2.3.
I have installed openSSL 1.0.2.j to compile the native tomcat-native-1.2.10 using apr-1.5.2 and tomcat-connectors-1.2.42 for the mod_jk. The problem is that tomcat seems to start but fails sometimes to connect correctly to apache and causes apache to hang. If I stop tomcat, apache starts working again. I have been through the logs with little indication of the problem. If I revet back to 8.0.32 everything works OK. All I can find is this in the mod_jk.log: [Sat Dec 17 06:11:48 2016][3212:47280261211024] [info] init_jk::mod_jk.c (3595): mod_jk/1.2.42 initialized [Sat Dec 17 06:11:50 2016][3254:47280261211024] [info] jk_open_socket::jk_connect.c (817): connect to 127.0.0.1:8009 failed (errno=111) [Sat Dec 17 06:11:50 2016][3254:47280261211024] [info] ajp_connect_to_endpoint::jk_ajp_common.c (1068): (worker1) Failed opening socket to (127.0.0.1:8009) (errno=111) [Sat Dec 17 06:11:50 2016][3254:47280261211024] [error] ajp_send_request::jk_ajp_common.c (1728): (worker1) connecting to backend failed.
