  When the number of user groups in the database query issued by
  Process Portal to populate the Task List dashboard exceeds
  1024, the "maxClauseCount is set to 1024" exception is reported
  and the Task List is not populated.
  

Problem conclusion

• A fix is available that increases the maximum number of user
  groups that can be specified in the task list query (to
  accommodate any practical number of user groups).
