Well that is a lot of swap for a server.. if something really starts
using that much swap its going to most likely end up in a bad race
where you are swapping out more stuff than you are getting in.  For
most large memory systems my rule of thumb is no more than 1:1 on
swap. Adding to 1 to 3 more GB of memory can fix some of these issues
sometimes because you have more room to stuff things in when trying to
swap stuff in.

Something is eating up swap. Not sure what it is from the message.. so
you are going to need to look in using some sort of script to track
whats going on and see if you can find out what is doing it.
