There are definitely some files with some weird names- in an ssh session they don't even have regular characters.
-rw-rw---- 1 xxx xxx 114985112 Oct 31 14:39 ▒^t
Not sure if that is related to problems though.
The top command shows
Memory: 12G phys mem, 343M free mem, 2048M total swap, 2048M free swap
This is in the evening so should not be much load but I think it was about the same earlier. Although I don't have a lot of free physical memory I am not eating into my swap file.

My guess is you have filenames on that share that are not utf8. Look inside:
