Hi,

We have an application which is developed on Apache trinidad 2.0.
we have the following setting in our web.xml -

<context-param>
    <param-name>javax.faces.STATE_SAVING_METHOD</param-name>
    <param-value>client</param-value>
  </context-param>
  <context-param>
    <param-name>org.apache.myfaces.COMPRESS_STATE_IN_SESSION</param-name>
    <param-value>false</param-value>
  </context-param>
  <context-param>
    <param-name>org.apache.myfaces.SERIALIZE_STATE_IN_SESSION</param-name>
    <param-value>false</param-value>
  </context-param>

 <context-param>
    <param-name>org.apache.myfaces.trinidad.CLIENT_STATE_MAX_TOKENS</param-name>
    <param-value>8</param-value>
  </context-param>
  <context-param>
    <param-name>org.apache.myfaces.trinidad.COMPRESS_VIEW_STATE</param-name>
    <param-value>true</param-value>
  </context-param>
  <context-param>
    <param-name>org.apache.myfaces.trinidad.CACHE_VIEW_ROOT</param-name>
    <param-value>false</param-value>
  </context-param>



Any idea why In high load during performance test for 150 concurrent user following exceptions are thrown.
