This is a real hardware server. It is not doing GIS or mapping of the
like, most of the DBs on this are for web sites, mostly form data
storage, some CMS DBs for joomla, WP, etc. also some others for cacti
and powerdns backends.

I have setup some scripts to watch the swap usage to see if I can track
this down.

Thanks for the help
