No, definitely not.  VIRT is everything the process has ever touched,
including shared memory and all libs whether or not they've actually
been loaded or not.  It's not uncommon to have literally a hundred
processes with 8G+VIRT on my 32Gig db servers, because most of that 8G
is shred buffers.  It's not using that much memory individually, it's
using shared_memory, and each process reports that it has access to
and has touched that 8G.
