Symptoms

Application intermittently fails with session expired error in browser and logs shows:

But session-timeout in web.xml is 6000 and session shouldn't end. Hence, it seems that the session is not expiring but the page state instead, and then the tokens are not being found during navigation.
The application has set org.apache.myfaces.trinidad.CLIENT_STATE_MAX_TOKENS to 3600 which is more than enough, so it is not likely the application is running out of tokens.

With further debugging it was seen that the token associated to the session-id for some unclear reason is not found later.
