we just migrated from JBoss 3.0.4 to JBoss 3.2.3. There seems to be some connection leak inside JBoss ( we did not change any code ), but it could be that I've configured things wrongly so here's a sample config
( I got this to work ), the problem only occurs when many of the developers are connecting at the same time. We have about 5 machines running ( non of which is doing anything strenuous ) when we see that the total connection to the database ( from all machines ) exceeds the maximum allowable ( set by the database ). Anything missing ?
