1) I am moving from mod_proxy_ajp back to mod_jk tonight so after than I can be more sure of sticky sessions working because I know they work for sure in mod_jk. I know they are not working correctly now, although I have it setup just like the Wiki explains (http://wiki.jboss.org/wiki/Wiki.jsp?page=UsingMod_proxyWithJBoss). I have this in my configuration: | ProxyPass /ATS balancer://bmcluster stickysession=JSESSIONID lbmethod=bytraffic nofailover=Off But subsequent requests are getting distributed between server A and B. 2) The system is not under load at all, but I see your point. I originally setup REPL_ASYNC with StickySession because latency wasnt a consideration. I totally understand why the message is beging generated and I see 2 possible solutions a) Get Sticky Sessions working properly with REPL_ASYNC b) Use REPL_SYNC without sticky sessions Do you concur?
