hi,
I am quite new to IIS which I put in place instread of Apache httpd. I use IIS to front Tomcat/JBoss instances using isapi_redirect (Tomcat connectors). IIS works great comparing to Apache in terms of performance, but still I got some issues I cannot solve. Let me shortly describe my structure:
IIS fronts 8 Tomcat nodes (workers) like this:
node 1 - Application A
node 2 - Application B
node 3 - Application C
node 4 - Application D
node 5 - Application E
node 6 - Application E
node 7 - Application E
node 8 - Application E
Nodes 5 to 8 contain same application and IIS balances the load (sessions are not replicated, sessions are sticky). The problem is, when I restart e.g. node 7 the whole IIS goes down, I cannot access any Application (A,B,C,D or E). I could not reproduce that in my test environment - perhaps that is somehow connected to the load (traffic)? AJP and worker.properties settings (timeouts etc.) are exactly same as used on Apache, where it was not the problem.
I cannot find any helpful entries in event viewer or logs.
Any ideas mostly appreciated, thanks in advance.
