[SOLVED] zram-generator terminated error issue

athan · 2024-12-09 10:17:32

What does the following error message in the journal mean?
I first noticed it after zram-generator was updated today.

(sd-exec-[419]: /usr/lib/systemd/system-generators/zram-generator terminated by signal ABRT.

If you want to know *why* it aborted w/o providing any context: because you did something wrong

Yes, I did something very wrong, I answered "Yes" when pacman -Syu showed today's update of the zram-generator...
Thanks for the helpful answer.

What do you expect? Magic knowlege about the issue?
https://bbs.archlinux.org/viewtopic.php?id=57855

Edit, to maybe get this anywhere: an ABRT is a controlled exit.
There's probably some message in the system journal or the service status explaining it and perhaps some https://wiki.archlinux.org/title/Core_d … _core_dump to tell what's going on.

It's a minimal archinstall installation without any manual intervention or configuration of zram or swapping in general.
It worked fine with the zram created defaults until today. After zram-generator package was updated earlier it stopped working returning this error message.

I'm sorry I can't give more details but that's all it happened.

PS: If it helps, trying to manually start the zram service (sudo systemctl start systemd-zram-setup@zram0.service) I got the following error

Yes you can, start w/ your /etc/systemd/zram-generator.conf and the "systemctl status systemd-zram-setup@zram0.service".
Then check for coredumps.
And again: there's gonna be context to this in the system journal where you found that line tbw.

athan · 2024-12-09 14:37:49

/etc/systemd/zram-generator.conf as created by archinstall contains just the device name apparently using zram defaults for the rest

[zram0]

Also tried with some values with exactly the same results

[zram0]
zram-size = min(ram / 2, 4096)
compression-algorithm = zstd

systemctl status systemd-zram-setup@zram0.service

Please don't copy-paste out of the pager but that looks like some code bug (miscast access, interpreting a string as something else or whatever) you should report at https://github.com/systemd/zram-generator/issues

In the end, the solution to the issue seems to have been simpler than it first appeared.
After a pacman -Rs zram-generator and reinstalling it from scratch everything works normally. I guess the latest update somehow messed things up.

seth · 2024-12-09 17:18:32

That's kinda odd, did you re-install rust along?

Please always remember to mark resolved threads by editing your initial posts subject - so others will know that there's no task left, but maybe a solution to find.
Thanks.

Nope, just the zram-generator.
Rust is make dependency, so it was not installed with the zram-generator binary package.

Thanks!
