Hi all,
I run a tiny and lightweight Debian 9.9 LXC container on Proxmox 6.2-6.
It has 512 MB of memory and 512 MB of swap assigned and typically needs
50-100 MB to operate.
Last year I started seeing about half of swap being used with very
little use of RAM.
I then made the following changes:
/etc/sysctl.d/60-my-swappiness.conf
vm.swappiness=10
/etc/sysctl.conf
vm.swappiness=10
and rebooted.
The container was running like that for several months until this
morning when its core service (dhcp) started failing.
I logged in to investigate and noticed 100% of swap being used with
maybe 10-20% of RAM in use.
Before I had time to look into details the container crashed (powered off).
I'll probably try to get rid of swap entirely as an experiment to see
what happens.
Unless somebody has any better ideas and hints?
Regards,
Adam
