Hi, I had installed postgreSQL v9.2 in Windows XP SP3. My PC specs: Processor: Pentium Dual Core 2.09 GHz RAM: 2GB The postgreSQL is run as windows service (manual). The problem is the postgreSQL service uses a lot of memory and lags the OS if running in long time (about 2 hours or more) so I had to restart the postgreSQL service everytime it happened. I never do any big querying process so far. I only ever run it for adempiere ERP software and a small struts 2 project. See this screenshot link from the Process Explorer: http://i45.tinypic.com/vr4t3b.png You can see that there are a lot of threads spawned. Is the threads that caused the high memory usage? Is there a way to decrease the memory usage?
