[Bug 1635194] Re: Issues when activating a large number of applications at the same time
I've closed this bug. The root cause was a kernel configuration option that used excessive memory for each mounted squashfs file. This has been fixed long ago now. ** Changed in: snap-confine Status: In Progress => Invalid ** Changed in: snap-confine (Ubuntu) Status: New => Invalid ** Changed in: snap-confine Assignee: Zygmunt Krynicki (zyga) => (unassigned) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1635194 Title: Issues when activating a large number of applications at the same time To manage notifications about this bug go to: https://bugs.launchpad.net/snap-confine/+bug/1635194/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

This was traced to running out of memory and addressed via kernel bug https://bugs.launchpad.net/snappy/+bug/1636847 There may be an issue left to investigate that affects core systems and /writable. I will add a spread test and either close this issue (via duplicate link) or work on a remedy for /writable. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1635194 Title: Issues when activating a large number of applications at the same time To manage notifications about this bug go to: https://bugs.launchpad.net/snap-confine/+bug/1635194/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Coincidence; there were over 200 loopbacks active in the system. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1635194 Title: Issues when activating a large number of applications at the same time To manage notifications about this bug go to: https://bugs.launchpad.net/snap-confine/+bug/1635194/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 1635194] Re: Issues when activating a large number of applications at the same time
Once upon a time the Linux kernel defaulted to only 16 loopback mounts at a time; is that still the case? Or is it a coincidence that your paste shows 16 loopbacks in use?

[Bug 1635194] Re: Issues when activating a large number of applications at the same time
It seems this bug affects core systems only (this is just a theory) and the solution is to make a few more things unbindable. I'm investigating the cause right now. ** Changed in: snap-confine Importance: Undecided => Critical ** Changed in: snap-confine Milestone: None => 1.0.45 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1635194 Title: Issues when activating a large number of applications at the same time To manage notifications about this bug go to: https://bugs.launchpad.net/snap-confine/+bug/1635194/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
