| Hi, We are facing a weird issue with Apache Gateway time out. We have deployed out application on two wildfly application servers using Apache as a load balancer. This application communicates with another application which is also using same configuration Apache load balancer and two wildfly application servers. 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.

| mod_manager is a third pary module. Is there anything the the docs of that module about that? 
 The normal way would be the use of mod_proxy_ajp and mod_proxy_balancer.
