I have lot of memory (32Gb) on my laptop though still have issues with having amount of free memory. I am using linux (Fedora 27) and this happens after while since reboot.
If you check free output, found, that memory looks ok and that there 19Gb cached memory which theoretically should be freed on demand:
# free -h
total used free shared buff/cache available
Mem: 30G 10G 419M 768M 19G 624M
Swap: 999M 999M 280K
But i tried to start virtual machine which should get 2Gb of memory and got "Cannot allocate memory".
Looked at cat /proc/meminfo and found that most of cached memory went to Slab - SUnreclaim point:

I have lot of memory (32Gb) on my laptop though still have issues with having amount of free memory. I am using linux (Fedora 27) and this happens after while since reboot.
If you check free output, found, that memory looks ok and that there 19Gb cached memory which theoretically should be freed on demand:
# free -h
total used free shared buff/cache available
Mem: 30G 10G 419M 768M 19G 624M

But i tried to start virtual machine which should get 2Gb of memory and got "Cannot allocate memory".
Looked at cat /proc/meminfo and found that most of cached memory went to Slab - SUnreclaim point:

I have lot of memory (32Gb) on my laptop though still have issues with having amount of free memory. I am using linux (Fedora 27) and this happens after while since reboot.
If you check free output, found, that memory looks ok and that there 19Gb cached memory which theoretically should be freed on demand:
# free -h
total used free shared buff/cache available
Mem: 30G 10G 419M 768M 19G 624M
Swap: 999M 999M 280K
But i tried to start virtual machine which should get 2Gb of memory and got "Cannot allocate memory".
Looked at cat /proc/meminfo and found that most of cached memory went to Slab - SUnreclaim point:
