Page not found error - Session Termination

Question

Hi
We are using SSL termination at web dispatcher (version 720 - patch 85).
The link is like
User < https> WD < http> Consumer Portal <https> WD <http> Producer
Portal <https> WD <http> Backend ABAP system
MSS > team > performance management and when they click on the overall
performance rating we get the "Page not found or not available"
Please note this happens intermittently
Our Dev Consumer portal has two server nodes, when we shutdown one node (say node0) and tested it out with node1 it works fine, then we switched off the server node1 and started server node 0, it works fine.
When both the nodes are up, it fails intermittently. From the session cookie we can find that if the request does a node hopping it fails and it happens intermittently.
Also when we tested the same directly on the producer portal it works fine.
We checked the parameters for both the server nodes, its the same.
Has anyone faced this kind of issues?
Regards
Senthil

Usually in this tortuous  route, limited Timeouts Parameters will trigger 404's and some times when you use Web Dispatcher caching but I don't think you have WD Caching.
    icm/conn_timeout   -
> From ICM to Client, this should be large enough , our Value 10000 (10 seconds)
    icm/keep_alive_timeout  --> Network timeout  180 ( 3 minute)
icm/server_port_0 = PROT=HTTP,PORT=1080,TIMEOUT=600,PROCTIMEOUT=1800 -
> Session timeout.
Can you post your values here.
Thanks
