Hi all. 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). Thanks. -- Best Regards! Wen Dong --------------------------------------------------------------------- The official User-To-User support forum of the Apache HTTP Server Project.
