Cause
The WebSphere Application Server had been recently upgraded from version 6.0.2.17 to a post-6.0.2.23 version.
 
Answer
In the installation instructions for IBM Workplace Collaborative Learning fix pack 2.7.0.5, there is a specific post-installation procedure for deployments using the WebSphere Application server version 6.0.2.23 or greater, as follows:
Post-install instructions: Section (e) For Deployments using WAS 6.0.2.23 or greater:

(1) Log into the Administrative console.

(2) Select Resources and expand '"Cache instances".

(3) Click "Object cache instances".

(4) Click New (halfway down the page).

(5) Add the settings as follows:
    - set "Name" to "learningcustbehavior" .
    - set the "JNDI name" to "services/cache/learning/behavior" .
    - set the cache size to 100 (must be in the 100 to 2000 range) .

(6) Click Apply.

(7) Click the Save link at the top of the page.

(8) Click Save.

(9) Restart the server .
    This fixes an issue with the dynamic cache.

You can download the Workplace Collaborative Learning fix pack 2.7.0.5 and its documentation from Fix Central at http://www-933.ibm.com/support/fixcentral.
