I'm using Suse 10.1 with an AMD dual core processor and 850MB memory (note: There's 1000MB of ram but 150MB is shared with the video card thus leaving the system to recognize only 850MB) MonetDB softwares used are the packages presently posted on: http://monetdb.cwi.nl/testing/projects/monetdb/Stable/.DailyBuilds./RPMs/SuS... With the table, "test" having 4 million rows using sql and jdbcclient: geo->select column1 from test; It displays the column1 query results for about 10 seconds and then the jdbcclient-1.4.jar crashes leaving the following message before it bugs out: Exception in thread "main" java.lang.OutOfMemeoryError I tried many many combinations of java options concerning memory and gc to try to fix it but in my hands, no luck. I worked around this by switching to the MapiClient which works just fine. Just thought there might be some interest in these results. Thanks to everyone again.....George
