Dear all we have deployed our university application in a cluster(did load balancing using AJP) using tomcat application servers and apache access sever.
*Following is our apache httpd.conf configuration* ProxyPass / balancer://myCluster/ stickysession=JSESSIONID|jsessionid nofailover=On timeout=60 <Proxy balancer://myCluster> BalancerMember ajp://192.168.1.2:8009 route=sys02 BalancerMember ajp://192.168.1.3:8009 route=sys03 </Proxy> In *apache access server error log* we are getting following errors, and these errors *started today*, before today our system was running smoothly, *periodically user getting error "service temporally unavailable"* when users reporting this issue then we are resolving it by restarting apache access server. However our tomcat instances are running fine. [Thu May 12 18:13:32 2011] [error] proxy: BALANCER: (balancer://myCluster).
