Nobody else has answered to this, so I give it a try.
(Maybe someone else is wondering about the same thing and
finds this when grepping the archives.)

There is no problem, and there is no bloat.

"VSZ" is the virtual size of the process, that is, all memory
that the process has requested.  It does not mean that actually
that much memory has been allocated (in RAM/swap) -- that's
only done if and when the process actually _uses_ those pages
of memory.

In the case of rpc.rstatd, only a small fraction of the memory
associated with the process is actually used (usually < 1 Mb).
I don't know why it requests that much memory (maybe it makes
handling the status data easier...  well, you have the source).

In your case, the process is even completely swapped out:  RSS
is zero ("resident set size", I think).  It probably has been
inactive for quite a while.

Regards

PS:  Maybe this should be in the FAQ...?
