** EXTERNAL EMAIL **
Hi to all,
I have a virtual server centos 7.3 with posgres 9.5.7 and I have a problem with huge swap usage.
In this moment I have 0 GB of free swap and 6,5 GB of RAM free.
My swappiness is set to 30 (as default) and the page size is 4 kB.
Is there someone that can help me to solve the problem?
Below my server configuration.
Thanks
