This failure occurs in the cloud, on amazon aws, it can be reproduced on c4/c5.large abd c5.metal where it passes on c5n.xlarge / i3.metal m3.large m4.large. I will try the suggested steps above on one of the affected flavor types and see if we can get to the bottom of this. ** Changed in: ubuntu-kernel-tests Assignee: (unassigned) => Sean Feole (sfeole) ** Tags added: sqa -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to systemd in Ubuntu. https://bugs.launchpad.net/bugs/1783881 Title: ltp-syscalls: msgstress03 fails because systemd limits number of processes Status in ubuntu-kernel-tests: Triaged Status in linux package in Ubuntu: Incomplete Status in systemd package in Ubuntu: Incomplete Status in linux source package in Xenial: New Status in systemd source package in Xenial: New Status in linux source package in Cosmic: Incomplete Bug description: As systemd limits the number of processes, this test will fail because it can't fork enough processes.

[Touch-packages] [Bug 1783881] Re: ltp-syscalls: msgstress03 fails because systemd limits number of processes
Hi,
I recommend you to change your test system.
For example, you can modify /etc/systemd/system.conf and change DefaultTasksMax
there. But that is for the systemd started units...
Note that TasksMax these days can accept % values of kernel configured max
tasks too, meaning i.e. one can set it to 100%. The upstream default is 15%
and we reverted that, meaning setting it to unlimited.
However something odd is going on.
I wonder if you are actually hitting UserTasksMax instead (which appears
to be under-documented).
I wonder if setting UserTasksMax=100 in /etc/systemd/logind.conf in
the [Login] section, restarting systemd-logind, creating a brand new
user session (logout _all_ sessions, and relogin) would actually solve
your problem?
ps. Also you can use a "drop-in" instead of modifying a config file, as all
config files in systemd support .d `drop-ins` like so:
instead of modifying /etc/systemd/system.conf one can instead install
files like these:
/{lib,etc,run}/systemd/system.conf.d/bump-tasks-max.conf
with like contents of
[Manager]
DefaultTasksMax=100
Depending on whether you want it to be packaged in a package, be a
config file, or be a runtime adjustment.

[Touch-packages] [Bug 1783881] Re: ltp-syscalls: msgstress03 fails because systemd limits number of processes
The number of processes (in systemd, tasks). The command below works for me. Now, should we change the default on our test systems? Running under systemd-run does not look like a good option. # systemd-run -p TasksMax=100 ./testcases/bin/msgstress03 -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to systemd in Ubuntu. https://bugs.launchpad.net/bugs/1783881 Title: ltp-syscalls: msgstress03 fails because systemd limits number of processes Status in ubuntu-kernel-tests: New Status in linux package in Ubuntu: Incomplete Status in systemd package in Ubuntu: Incomplete Status in linux source package in Cosmic: Incomplete Status in systemd source package in Cosmic: Incomplete Bug description: As systemd limits the number of processes, this test will fail because it can't fork enough processes.

[Touch-packages] [Bug 1783881] Re: ltp-syscalls: msgstress03 fails because systemd limits number of processes
What about calling it like this: $ sudo systemd-run ./testcases/bin/msgstress03 Does that make it pass correctly? Which resource in particular is exhausted? and can it be toggled somehow using any of https://www.freedesktop.org/software/systemd/man/systemd.directives.html ? ** Changed in: systemd (Ubuntu Cosmic) Status: New => Incomplete -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to systemd in Ubuntu. https://bugs.launchpad.net/bugs/1783881 Title: ltp-syscalls: msgstress03 fails because systemd limits number of processes Status in ubuntu-kernel-tests: New Status in linux package in Ubuntu: Incomplete Status in systemd package in Ubuntu: Incomplete Status in linux source package in Cosmic: Incomplete Status in systemd source package in Cosmic: Incomplete Bug description: As systemd limits the number of processes, this test will fail because it can't fork enough processes.
