I'm using httpd 2.2 and websphere application community edition (wasce) 2.1.1 (you may treat it as tomcat if you are not familiar with wasce). My goal is: the httpd server delivers 3000 requests per second to the wasce servers. I use the mod_jk module, and the workers.properties conf like this: ... worker.node5.port=8009 worker.node5.host=9.186.96.71 worker.node5.type=ajp13 worker.node5.connection_pool_size=50 worker.node5.connection_pool_minsize=25 worker.node5.connection_pool_timeout=600 worker.node5.lbfactor=1 worker.loadbalancer.type=lb worker.loadbalancer.balance_workers=node1, node2,node3,node4,node5 worker.loadbalancer.sticky_session=1 worker.loadbalancer.sticky_session_force=0 now the question is, I'm using mod_jk as the load balancer server. when users' requests increase (more than 1000requests per second), there are many warnings in the mod_jk.log: [Tue Mar 24 15:36:37 2009] [14425:735282400] [warn] ajp_get_endpoint::jk_ajp_common.c (2946): Unable to get the free endpoint for worker node3 from 50 slots [Tue Mar 24 15:36:37 2009] [14425:4059268320] [info] service::jk_lb_worker.c (1161): could not get free endpoint for worker node3 (0 retries) and the performance of httpd reduce. I want to know is there anybody having the SAME SITUATION or someone knows is there any error in my worker.properties configuation (which causes the could not get free endpoing error).
