The task > counter should also report the total heap usage of the task also. The task > might be configured with a max heap size of M but the task's total heap usage > might only be H, where H < M. In such a case, knowing only M doesn't provide > a complete picture of the task's memory usage. -- This message is automatically generated by JIRA.
