krillin #169 + cgroups fix, scopes hang / crash / unusable

[Alan Pope 🍺🐧🐱 🦄]

On a couple of occasions over the weekend my phone has become unusable. I can unlock it, swipe the launcher out, pull down indicators, launch applications (from the launcher) and switch applications from the side. I cannot use any scops. They don't respond to touch at all. I'm stuck on the "Today" scope.

i have seen this without the cgmanager change on 169 too

[Michi Henning (michihenning)]

Added unity8, because that might also be involved.

A stack trace would be super-useful, both of the stuck scope, and of unity-shell.

Do you have any suggestions for how to reproduce?

[Albert Astals Cid (aacid)]

Is this something you guys have seen recently?

[Michi Henning (michihenning)]

I suspect it's a moldy oldie by now. No-one has reported anything similar since this issue was opened, and we don't have enough information here to act on anything.

[Albert Astals Cid (aacid)]

Following Michi's comment and the fact that noone seems to have seen this recently i've put both bugs as Incomplete so that the bug gets expired in 59 days if noone comes up with more information.

[Quentin Quaadgras (quentin-d)]

I can confirm this has happened to me, scopes froze up for a couple minutes then started working again

[Albert Astals Cid (aacid)]

Has nothing to do with this bug then, yours seems as if scopes crashed and then restarted, please report a new bug.

[Neil McPhail (njmcphail)]

I'm adding a comment to keep this alive. I have had this bug on occasion on krillin rtm v20. I haven't had an episode since upgrading to v21 a couple of days ago but can't see anything in the changelogs which suggest it has been fixed. If it has been fixed in the meantime, sorry for the spam but this bug should then be closed.

[Albert Astals Cid (aacid)]

Unless you know your issue is because of cgroups as the subject says, don't write anything in here. Open a new bug and describe your problem in there.

[Michi Henning (michihenning)]

Closing this because, by now, this is almost certainly a non-bug.

[Expired for unity8 (Ubuntu) because there has been no activity for 60 days.]
