Debian 10 (Buster) Memory problems ?

[Luiz Gustavo Sarubi Macchi]

Hi all,

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. 

Second, sometimes it happens that some program crashes or fails to segment and then the system triggers Ram memory to the end and starts using Swap, the result is the whole system crashes. did anyone notice that too?

$ sudo sysctl -a|grep swappiness

vm.swappiness = 0

thanks in advance
