Re: memory eating

free memory is bad memory

if there is no running application reclaiming the ram ( which is your case here ) , the kernel allocates the remaining memory to cache the data from the filesystem, so as to make the disk access faster

as soon as applications require more memory the kernel will allocate what they ask, and reduce the amount of memory used for the disk cache

so what you see is perfectly normal

    The memory is just going to the disk cache. The system will release it
    if something actually needs it. Otherwise, free memory gets used as
    cache. There doesn't appear to be any evidence it's swapping.
