Hi,

We are facing a weird issue with Apache Gateway time out. We have deployed our application on wildfly cluster(2 nodes) using Apache as a load balancer. This application communicates with another application which is also using same configuration Apache load balancer and wildfly cluster (2 nodes). 3 out of 5 time we are facing HTTP-500 gateway time out error, when application tries to hit the load balancer URL of another application. I also tried to increase the TimeOut directive and added node-timeout attribute as mentioned on https://access.redhat.com/solutions/772613 but still same issue.

Any pointer will be helpful.

httpd.conf file.
