Starting around 7/28/2017 the SwapUsage started to climb for reasons I cannot figure out. I have spent many hours Googling and reading AWS documentation. At no point do we run out of FreeableMemory.

Does anyone know what could cause this? There doesn't seem to be a performance hit as far as I can tell, but from what I've read there should be no swap usage at all, so I don't want to just ignore it.
I hope this is enough information, let me know if anything else would be helpful. Thanks in advance for any assistance.
