October 30, 201213 yr Using Simplefeatures I've noticed that upon transfering data to my server RAM useage spikes and stays high afterward. Almost like it is using the Ram for a cache drive and never clearing it. I have 8GB and it's useage is over 7 constantly. I've only seen one mention of something similar anywhere and not sure where to start.

I've only seen one mention of something similar anywhere and not sure where to start. Start by ignoring it. It is not freeing memory because nothing else needs it. It will ALWAYS keep the most recently accessed blocks of data in memory (it is the disk buffer cache) That way, if you rewind on a movie, or re-invoke a program you constantly are using, it does not even have to go to the disk to access it. All Linux is designed this way. It has nothing to do with SimpleFeatues, the same memory usage will occur if you play a 4GB movie. (It, because it is most recently data accessed will displace the least recently accessed data in memory, but your memory will still show high usage in buffer cache.) What does free -l show? If anything unRAID will run out of "low" memory if you run too many add-on processes. It is probably the most critical to watch.

It is working as designed.
October 31, 201213 yr Probably one of the most common "AHHHHH!" moments for new linux users - and most think "I need to buy more RAM - FAST", but like Joe said - all is well. http://www.linuxatemyram.com Also, I installed htop, and it was an eye-opening experience for learning about how linux manages RAM. http://lime-technology.com/forum/index.php?topic=4636 Cheers whiteatom
