Dear Community I hope your all doing well today. Thank you for assisting me the other day with setting up SSL properly. Recently, I have been running into an issue where HTTPD load balancing falls over, thus preventing me from reaching the Tomcat sessions. The error messages that I am getting are below: [Sat Jul 16 14:33:00 2016] [error] (120006)APR does not understand this error code: proxy: read response failed from (null) (xxx.xxx.xxx.xxx) [Sat Jul 16 14:33:13 2016] [error] (70007)The timeout specified has expired: ajp_ilink_receive() can't receive header [Sat Jul 16 14:33:13 2016] [error] ajp_read_header: ajp_ilink_receive failed [Sat Jul 16 14:33:13 2016] [error] (70007)The timeout specified has expired: proxy: read response failed from (null) (xxx.xxx.xxx.xxx) [Sat Jul 16 14:33:16 2016] [error] (70007)The timeout specified has expired: ajp_ilink_receive() can't receive header [Sat Jul 16 14:33:16 2016] [error] ajp_read_header: ajp_ilink_receive failed OR [Sat Jul 16 14:35:56 2016] [error] (120006)APR does not understand this error code: proxy: read response failed from (null) (xxx.xxx.xxx.xxx) [Sat Jul 16 14:35:56 2016] [error] (104)Connection reset by peer: ajp_ilink_receive() can't receive header [Sat Jul 16 14:35:56 2016] [error] ajp_read_header: ajp_ilink_receive failed The current configuration for load balancing (not mine), copied straight from the file, looks like: ProxyPass / balancer://mycluster/ stickysession=JSESSIONID <Proxy balancer://mycluser> BalancerMember ajp://xxx.xxx.xxx.xxx:port1 route=Node1 loadfactor=50 BalancerMember ajp://xxx.xxx.xxx.xxx:port2 route=Node2 loadfactor=50 </Proxy> After spending some time Googling and reading, I have now re-written the configuration to look like the following: ProxyPass / balancer://mycluster/ stickysession=JSESSIONID <Proxy balancer://mycluster> BalancerMember ajp://xxx.xxx.xxx.xxx:port1 route=jvm-Node1 loadfactor=1 connectiontimeout=10 retry=600 BalancerMember ajp://xxx.xxx.xxx.xxx:port2 route=jvm-Node2 loadfactor=1 connectiontimeout=10 retry=600 </Proxy> <VirtualHost subdomain.domain.ac.za:80> ProxyPass / balancer://mycluster/ ProxyPassReverse / balancer://mycluster/ </VirtualHost> Will this address the issue at hand or is there another reason for the errors that I am getting?
