After a restart the Custom Managed Server running WebCenter Portal Applications, HTTP-404 errors are randomly seen. 

• This is in a 3 node cluster installation with a Custom SSO Authentication plugin is installed in the WebLogic Server cluster.
• The WebCenter Portal is behind this Custom SSO authentication Plugin and delegates through the ADF authentication layer the authentication to it.
• The load test works fine on the test system but this system has a restriction to 40 users.
• The load test doesn't work on production system with 60 and more users,  There are a lot of threads hangings and the http session replication is not working.

The following errors reported in the managed server log file:

<BEA-000117> <Received a stale replication request for object -<OBJECT_ID>.

Followed by warnings:

<Warning> <HTTP Session> <www.oracle.com> <[ACTIVE] ExecuteThread: '4' for queue: 'weblogic.kernel.Default (self-tuning)'> <> <> <> <ID> <BEA-100094> <The session id: <SESSION_ID> has been accessed from  WSC:WSC_portal_manager1, a server that is not the primary (....0:). The request URL was: https://<HOSTNAME>:443/test/test/blank.html>

Many sessions do not have the replica set in the session information:

• The configuration in place has policy store in the file system.
