 |
|
Has anyone seen x11-misc/lightdm-1.10.5 leaking memory?
I don't really monitor my server that much, and usually leave it logged out with lightdm started. Today I noticed
| Code: | PID USER PR NI VIRT RES SHR S %CPU TIME+ P SWAP COMMAND
3987 qemu 20 0 4655568 1.153g 1388 S 0.7 969:36.68 2 238828 qemu-system-i38
4987 root 20 0 1626552 990.9m 3088 S 0.0 89:03.54 3 352148 lightdm-gtk-gre
3635 qemu 20 0 2314432 91196 1296 S 0.3 213:06.82 3 350360 qemu-system-i38

I have 6GB RAM in the system and since I only have one large VM running at the moment, it's not a big deal, but it shouldn't be using nearly 1GB of RAM?
I suppose a restart of lightdm will clear it up. Uptime = 49 days, but unsure when I logged into the console last.
[EDIT]
Yes it is leaking very slowly, Not sure what's causing it to leak but after checking it again, the resident size has increased.
Restarting it got it back down to 35MB resident, 288MB virtual.
[EDIT 2]
After almost a day, it has increased to 48MB resident, 302MB virtual.
Looks like it leaks around 16MB/day, which is pretty close to what I saw yesterday before restarting.
And a link: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=734526 but it refers to an old fixed bug? Though the rate of leakage is similar to what I see...

My reading of the bug report you reference, and indeed your top excerpt indicates it's the greeter that leaks, x11-misc/lightdm-gtk-greeter. It is a separate package/ebuild.
The stable version of the greeter is 1.6.1, the bug report indicates that this problem is fixed in 1.8.2, but not 1.7.0. I see that 1.9.0 (2.0.0, 2.0.1) is available in portage, you could unmask and test this version. |

Ahh... Thought they were the same package, so this makes more sense now. Might need to get the gentoo devs to unmask a newer version.
Installed 2.0.1-r1 which is worse off the bat (384MB virt, 95MB RSS) but hope this won't leak further... we'll see in a few hours...
[edit]
Filed https://bugs.gentoo.org/show_bug.cgi?id=571960 as it looks like it's no longer leaking.
