MEMORY USAGE

#1

Post by giorgosperi » 15 Jan 2016 05:09

Hello, i have a question if anybody knows...i dont know if i am writing on the right topic
I am running nas4free 10.2.0.2 just i have a small issue...after some use i check the system and the memory usage stays always 78%. I dont think that its actually uses this memory, maybe it doesnt "empty" the memory?
Do you have any idea why this is happening or if you need more information...Thanks

That is normal behaviour, if you use ZFS, as all available memory is used as cache.
