I am having this problem occasionally as well. 
Solution is either a gc() or restart of r terminal . I also notice that it occurs when I am trying to open up fourth or fifth instance of the connection without closing earlier ones.

nothing else but R and Bloomberg running -- or if you've already run
other commands.
