Re: [SOLVED] systemd 250 error log

I have the same warnings generated by dbus-daemon. Fully updated Arch Linux stable branch, stock kernel.

@seth

Re: [SOLVED] systemd 250 error log

for PID in $(pidof dbus-daemon); do printf "$PID : "; cat /proc/$PID/oom_score_adj; done
427 : 100

If I dump dbus-broker it reports me a systemd-resolved error which I have activated.

Re: [SOLVED] systemd 250 error log

What helps the three people reading this thread

This thread has 1,016 views, so I think there are more people reading it then just the 3 (well, 4 now) posters .
I'm also subscribed to the systemd bug and looking forward to new contributions to it.

Disliking systemd intensely, but not satisfied with alternatives so focusing on taming systemd.

Re: [SOLVED] systemd 250 error log

@Fixxer - there's the 200

ps u 752 715

@robson, dbus-broker is absolved because Fixxer doesn't have it.
Why's there only one process w/ now 100?

ps u 427

Re: [SOLVED] systemd 250 error log

That's the session bus, but why is it only at 100? Does OOMScoreAdjust stack the values?
Can you

echo 50 > /proc/427/oom_score_adj

?

Re: [SOLVED] systemd 250 error log

No error means "worked" and that means the "100" was somehow set on the process by your user.
Any idea how that might have happened?

But it's also weird that you don't have the -900 session bus (which has been there foralmostever)…

Ok. It's new session, as follows:

Re: [SOLVED] systemd 250 error log

261 is the session bus, that's not scary.
If you apply the "fix" from https://bbs.archlinux.org/viewtopic.php … 6#p2012166 - does the session bus (or at-spi's thing) end up w/ and adjustment of 0, 100 or 200?

Late coming back to this cluster f&^% party...

If you apply the "fix" from https://bbs.archlinux.org/viewtopic.php … 6#p2012166

Yes, it worked; but as expected, upgrade to systemd 250-4 put the damn thing right back.  Re-did the fix, and here we go:

I can write any arbitrary positive number as user to both /proc/$userPID/oom_score_adj, although negative numbers give a permission denied.

Re: [SOLVED] systemd 250 error log

negative numbers give a permission denied.

Perfectly normal - did you try to write the oom_score_adj on the dbus processes when they're at 200? Can you go down to 100? Lower?

IIRC, I could get the values down to 100, and anything lower came back with permission denied.
