Hi there,
I am starting to see these errors on one of my nodes, I searched the forum but can't find a definite answer.
I have plenty of ram and the drives are CMR, I don't get what can cause this, a weird behaviour is that the system will keep on running but the network will go, making it unreachable unless jumping on IPMI, restarting the networking service won't make a difference, but a full reboot will fix.
Running VM and containers are just using 45G RAM where my pool is 134G
