Hi Alex, What is the query being run and what is the compiler execution plan, see http://docs.openlinksw.com/virtuoso/fn_explain.html ?
What is the status of the server leading up to the out of memory error, please provide a few samples of running the “status(‘’);” command from isql before during and up to the point of the out of memory error, ditto for the Linux “top” command showing the process resource usage.
