It seems like there is not enough data in your mail... what data base are you accessing? how are you dealing with it (DataSource is JDBC or via the App Server) your class is keeping the data for any reason (maybe in a session or application bean)? what's the App Server? etc, etc... if i were you i should look all that kind of variables and monitor with a profiler to see if there's somehint wrong with the query, the server, the managed memory, or all of the above.

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 ____________________________________________________________________________________ ¡Capacidad ilimitada de almacenamiento en tu correo!
