The virtual size in "top" includes all the index data that the Solr
install is serving, as well as all of the actual RAM that's used.  I
have one server where VIRT for Solr is over 700 gigabytes, because
there's that much index data on the server.  Swap only has about 38MB
used, and I'm pretty sure that it is not Solr that has been swapped out.

I thought I sent a message about the lack of swap on Robert's server,
but I don't see it on the list.  I'm struggling with a new version of
Thunderbird, which ignores the Reply-To header when a message is from a
mailing list, so I have been sending a lot of unicast replies that skip
the list.
