Analizing de heap dumping, it's point for the same class allocating 600 Mb. This event can occur 3 hours or 3 days after I restart my server. This class is used thounsands times in the period. Monitoring the memory of the server, I could see 300MB to 700MB of memory been allocated in 3 minutes. It hapens eventualy but not in a determined period. The unique diference for this class for others, is the groupby clause in Ibatis. First I thouth it could be a cartesian product, but I ran the query without parameters and found nothing. I going to implement this class without groupby clause, but first I would like to see if there are other options. thanks, Fernando
