We are affected by this. Our elasticsearch process were getting killed even though we set xmx to half of the ram. Now reverting the kernel.

Precisely what I described. It's a web server that serves journald events/entries. It's separate from journald, and it's separate from systemd as a service. It's completely optional. It's no more embedded in systemd than nginx. It does exist in the same umbrella project as systemd, (and I think that is an issue) but embedded is the wrong term.
> embedded is the wrong term
Don't use it then. Anyway, since systemd-the-project doesn't have a separate name from systemd-the-init, I don't see any problem with Cieplak's statement.

#73It's not just a bunch of people setting cm.swappieness to 0 is it? That behaviour changed and now prevents going into swap /ever/ where it used to mean go into swap as a last resort. Changing it to 1 fixes the issue and will act like the old behaviour or only swapping as a last result.

Yeah, Ubuntu still keeps running out of space in /boot by filling it w old kernels in the default partition profile. A bug that I've been hitting since about 2011. In spite of their best efforts, it is not the "grandma friendly" quality software it hoped to be.
Yep, I had to fix a 14.04 server like that last week. /boot filled with old kernels and apt was falling. I had to manually fix that.
I also don't have swap on my laptop (16 GB RAM and SSD) and I rarely hit 10 GB of used space. With no swap I mean no swap partition. I'm getting those out of memory errors in Opera tabs since the new kernel. Luckily my primary browser (FF) is fine. I guess it's trying to swap Opera out even if there is no swap. I'll reboot with the older kernel and see what happens.

#74I stopped using Ubuntu after Amazon affiliate marketing showed up on the desktop. I stopped using Arch after I read the source code for SystemD. FreeBSD had quite a learning curve, but now it's on my laptops and is my preferred server OS. I love DTrace. I love ZFS. I love pf. I love Jails. I love ports, even though I generally use pkg. I love how easy it is to compile a kernel. The FreeBSD handbook is awesome. All th…
Do you Firefox? Because Firefox has Google as the default search engine which got them to receive hundreds of millions of dollars per year. Without that money,firefox would have been a lousy browser mainly by volunteers.
Ubuntu tried to do something with amazon but probably did not earn enough money and was scrapped for more than a year.

Funny, but Linux is the only unix-like OS I've ever run where using swap means you have a problem. Other OSes have much more intelligent memory management.
For me swap is an error. I would rather a server crash then go into swap and run slow. If your servers are at 75% CPU and start swapping you are screwed. Time to start adding servers. In this day and age you are wasting a lot of money to be sitting around waiting for swap.
zswap makes swap useful on the server as it results in gradual slowdown when the system has used all the ram. And if the system runs at 75% of CPU, then there is room for such slowdown.

I downvoted you for "grandma friendly." My grandma remembers when LaTeX was "new" and was one of the first people to professionally use computer-based typesetting. What exactly does "grandma friendly" look like to her?
I just wanted to say I think it's sad you're getting downvoted. My grandma was also relatively computer literate. If we ever hope to reach equality in our line of work we need to think more carefully about the personas[0] we use, not because our grandmas care but because of how such descriptions affects the people who might one day fall into that user category.

I used to use this to clean boot.
dpkg -l 'linux-' | sed '/^ii/!d;/'"$(uname -r | sed "s/\(.\)-\([^0-9]\+\)/\1/")"'/d;s/^[^ ]* [^ ]* \([^ ]\)./\1/;/[0-9]/!d' | xargs -p sudo apt-get -y purge

Exactly.
I have stopped using it long time ago, after they introduced the following bug:

My M.O. is: # apt-get update # aptitude full-upgrade # apt-get autoremove Because as far as I can tell, apt-get sometimes fails to actually update things, whereas aptitude can't autoremove. I'm sure there's a better way. This is my major gripe with the dpkg ecosystem. There are (AFAICT) multiple different tools to build dpgks and multiple different tools for updating your system, and none of them are adequately docum…
apt-get update won't do anything beyond download the latest view of the repository.
you want:
apt-get update && apt-get dist-upgrade && apt-get autoremove

What are the many missing packages on Debian? From my experience Centos looks like a bad joke.
Not sure what you mean, if RedHat/CentOS is good for Amazon to run their 2M linux nodes, it is probably good enough for me to host my services. The stability and production readiness of the platform beats all the other Linux distributions, especially Ubuntu and I would argue Debian too (hello purify complains bug).
