Debian 10 (Buster) and Swappiness

[Gustavo - Emar <suporte@emar.com.br>]

Hi,

After upgrading from Debian Stretch to Buster (10), we realize that it is not managing memory as before. 

First, even with Swappiness = 0 and having 32 Ram, (16 Gb using) it starts using Swap, and the system is slow and crashing. 

$ sudo sysctl -a|grep swappiness
vm.swappiness = 0

thanks in advance

Gustavo
