:) Its like this, My workers.properties file is as below worker.list=loadbalancer worker.loadbalancer.type=lb #worker.loadbalancer.balance_workers=server1,server2,server3 worker.loadbalancer.balance_workers=server2,server3,server4,server5 worker.loadbalancer.sticky_session=true # Set properties for worker 'server1' (ajp13) #worker.server1.type=ajp13 #worker.server1.host=IP1 #worker.server1.port=8009 #worker.server1.cachesize=10 #worker.server1.cache_timeout=600 #worker.server1.socket_keepalive=1 #worker.server1.reclycle_timeout=300 # Set properties for worker 'server2' (ajp13) worker.server2.type=ajp13 worker.server2.host=IP2 worker.server2.port=8009 worker.server2.cachesize=10 worker.server2.cache_timeout=600 worker.server2.socket_keepalive=1 worker.server2.reclycle_timeout=300 # Set properties for worker 'server3' (ajp13) worker.server3.type=ajp13 worker.server3.host=IP3 worker.server3.port=8009 worker.server3.cachesize=10 worker.server3.cache_timeout=600 worker.server3.socket_keepalive=1 worker.server3.reclycle_timeout=300 # Set properties for worker 'server4' (ajp13) worker.server4.type=ajp13 worker.server4.host=IP4 worker.server4.port=8009 worker.server4.cachesize=10 worker.server4.cache_timeout=600 worker.server4.socket_keepalive=1 worker.server4.reclycle_timeout=300 # Set properties for worker 'server5' (ajp13) worker.server5.type=ajp13 worker.server5.host=IP4 worker.server5.port=8009 worker.server5.cachesize=10 worker.server5.cache_timeout=600 worker.server5.socket_keepalive=1 worker.server5.reclycle_timeout=300 As you can see, Server4 and Server5 have the same IP (IP4) and both are jboss instances. On the IP4 server(linux box), i have copied two exactly same instances of Jboss. In the server.xml file of 1st jboss instance all configurations are default config (8080) whereas in the server.xml of 2nd jboss instance, i have changed port to 9080.Thats it. now when i start only 1st Jboss instance, it works pretty fine but when i start the 2nd instance, the application starts to crash. I have given XMX=XMS=1024m for both the instances and the server has 4 gb of physical memory. I can view the WEB-CONSOLE of 1st jboss instance and find 10 connections. I am not very clear if apache is actually using the 2nd instance and why does the application crash the error that i get is "Your Application session has expired or an unexpected error has occured!!!" Can anyone help me out ? :( -- View this message in context: http://www.nabble.com/Apache-with-multiple-instance-of-jboss-on-same-server-tp23979597p23981040.html Sent from the Apache HTTP Server - Users mailing list archive at Nabble.com. --------------------------------------------------------------------- The official User-To-User support forum of the Apache HTTP Server Project.
