[Building Sakai] Site Stats jobs that fail

Hi Sean,
Well, almost!
The quartz job is used only when the default SiteStats behavior is disabled
(which aggregates sakai events in real-time, using a thread). It processes
events from the sakai event table (SAKAI_EVENT), aggregating information on
SiteStats SST_* tables, and storing the last processed event id (from
SAKAI_EVENT) in SST_JOB_RUN.END_EVENT_ID. On the next run, the first event
to be processed from SAKAI_EVENT will be SST_JOB_RUN.END_EVENT_ID + 1.
Your confusion may come from the naming similarity from SAKAI_EVENT and
SST_EVENTS!
Hope it helps,
Nuno
