Redis_data e Postgres_data stanno consumando più di 20GB di spazio

As a general checkup, which includes a check for processes being killed due to shortage of memory:

@Ed_S

It feels possible that you have too little memory (by which I mean RAM+swap) and yet 2+4 should be enough. Please run the following quick diagnostics and post the results:

cat /etc/lsb-release
uptime
df -h /
free
swapon
vmstat 5 5
dmesg|egrep -i "memory|oom|kill"
ps auxrc
