navigating withing component takes back to search page

Hi,

Navigating between different tabs of the same component will take back to the search page 1 in 10 times. The incident is intermittent and has no definite pattern.This observation is taken from a single consistent session. When I noted this observation, I only had one browser and one session open against one peoplesoft environment.

I have implemented clustering of weblogic servers spread on two physical server with the following configuration:

server 1:

1 apache RPS

1 admin server

1 managed server PIA1

1 application server

server 1:

1 apache RPS

1 managed server PIA2

1 application server

Underneth the middleware lies RACK database.

Many thanks for looking into this issue.
