First time poster. I'm experiencing very similar symptoms. The system monitor shows my cached memory soaring to fill the entirety of my ram. I can manually reset my cached ram with
sync; echo 3 > /proc/sys/vm/drop_caches
from the command line, which has about 75% effectiveness of putting off the memory lag. The cached memory immediately begins to build up again, and it seems to only happen when I'm file-sharing.
