You're confusing virtual and real usage. The "virtual" space is what the application has requested, while RSS is the memory the application is actually using regularly and is therefore mapped to RAM. Judging RAM use by the Virtual value will result in severely inflated values, as you've seen. Note that applications will take more memory on sparc64 than on i386 due to larger data structures (64-bit integers and the like). -- Doug White | FreeBSD: The Power to Serve dwhite@gumbysoft.com | www.FreeBSD.org
