Yes. Something somewhere is leaking. It's not just with Debian 10.
I'm getting this on a Proxmox 5 host that has hardly any load at all with containers that have zero load:
Sep 04 05:41:19 pve12a kernel: Memory cgroup out of memory: Kill process 13694 (systemd-journal) score 279 or sacrifice...
Maybe I'm barking the wrong tree...
Maybe the problem was not with Debian 10 template but rather with Webmin that I used to manage Bind.
Same thing with Debian 9 template that I upgraded to Debian 10.
Conclusion: It's not the kernel and it's not the layer 1 option used in Debian 10 template until MySQL fix comes along because the Bind server does not have any need for nesting=1 option so I did not use it there? Anyway...
Noticed something else odd about Debian 10 LXC template.
It's the only template that somehow leaks text all over when using terminal and especially when using byobu.
Here is an example of two "normal" commands that only Debian 10 container mixes up.
Limit ZFS on Linux Memory Usage
echo "options zfs zfs_arc_max=1000000000" >> /etc/modprobe.d/zfs.conf
echo 1000000000 > /sys/module/zfs/parameters/zfs_arc_max
1073741824 is 1 GiB. It is good to use at most 50 percent (which is the default) of the system memory for ZFS ARC to...
There seems to be a problem with the new Debian 10 template.
I'm not just talking about it's failure to run MySQL but it also seems to hang easily.
Two different Bind9 servers (LXC) on two different (KVM) hosts have now hung after I moved them to run on the new template.
They show high CPU usage...
