Subject Re: Tomcat Memory usage(Urgent!)
Date Fri, 08 Mar 2002 11:04:35 GMT
within your program you might want to check out

Runtime runtime = Runtime.getRuntime;
runtime.freeMemory() vs
runtime.totalMemory()

This will let you know what it's really using..
But as top says it's only 59M then I'd be looking at
other processes in your ps list

Hope this helps
