------- Comment From [email protected] 2017-07-10 11:46 EDT------- This CMVC defect is being cancelled by the CDE Bridge because the corresponding CQ Defect [FW663285] was transferred out of the bridge domain. Here are the additional details: New Subsystem = ppc_triage New Release = unspecified New Component = ubuntu_linux New OwnerInfo = Chavez, Luciano ([email protected]) To continue tracking this issue, please follow CQ defect [FW663285].
Assigning for screening... It appears that the version of logind on this system does not support the value of "infinity", and is reverting to the default of 12288: # cat /sys/fs/cgroup/pids/user.slice/user-0.slice/pids.max 12288 As a workaround until this can be resolved, specify an exact value. You can try using the current system thread-max value: # cat /proc/sys/kernel/threads-max 3974272 /etc/systemd/logind.conf.d/htxlogindcustom.conf: [Login] UserTasksMax=3974272 Created mirror request (28237) Canonical Launchpad. Information on this bug will potentially be exposed to the public. Before you proceed, please make sure you read Content Guidelines for LTC Bugzilla : Confidential vs. Non-confidential[1]. [1] - ftp://ausgsa.ibm.com/projects/l/ltc/ToolsInfrastructure/ProjectStatus/Bugzilla/Bugzilla_Content_Education_v2.pdf The bug is ready to be mirrored to: Distro: Canonical Launchpad. Project: ubuntu Package: systemd This defect will go to Linux as even after making the below 2 changes in systemd resource limit, errors are seen: root@yellowbee:/etc/systemd/logind.conf.d# cat htxlogindcustom.conf [Login] UserTasksMax=infinity root@yellowbee:/etc/systemd/logind.conf.d# cat ../system.conf.d/htxsystemdcustom.conf [Manager] DefaultTasksAccounting=yes DefaultTasksMax=infinity root@yellowbee:/etc/systemd/logind.conf.d# logind limit for MaxUserTask as well as systemd limit was made infinite. Please look defect SW363655 for more details and the suggestion given earlier by Linux team. errors are still seen. So, would ask Linux team to take a look and see if anything else is causing these errors. == Comment: #3 - Kevin W.

Default Comment by Bridge This error recreated on the smaller 1U Open Power system with the same smaller 1-adapter/1-4U90 drawer/90 HDD.

It seems that your bug report is not filed about a specific source package though, rather it is just filed against Ubuntu in general. It is important that bug reports be filed about source packages so that people interested in the package can find the bugs about it. You can find some hints about determining what package your bug might be about at https://wiki.ubuntu.com/Bugs/FindRightPackage. You might also ask for help in the #ubuntu-bugs irc channel on Freenode. To change the source package that this bug is filed about visit https://bugs.launchpad.net/ubuntu/+bug/1651518/+editstatus and add the package name in the text box next to the word Package. [This is an automated message. I apologize if it reached you inappropriately; please just reply to this message indicating so.] Yet another mirror burp :-( Fixed on the LP side. It seems that more than just the package information was not set up properly during the mirroring. Luciano helped set the owner of the LP bug to Taco Screen team, so this bug will hopefully soon get some traction on the Canonical side. Thanks Luciano. The indicated upstream patch, f50582649f8eee73f59aff95fadd9a963ed4ffea, does not apply cleanly against systemd 229. Are there known prerequisites for this patch? It looks like the commit referenced earlier also builds upon the addition of the config_parse_tasks_max() function added in commit 6300502b . The following example patch (based on systemd_229-4ubuntu14) focuses on just the UserTasksMax "infinity" parsing. A test build of systemd with the previous patch applied resolved the parsing issue in my testing. # cat /etc/systemd/logind.conf.d/usertasks.conf [Login] UserTasksMax=infinity # cat /sys/fs/cgroup/pids/user.slice/user-0.slice/pids.max max cde00 ([email protected]) added native attachment /tmp/AIXOS06698101/systemd_infinity.debdiff on 2017-01-07 20:22:29 cde00 ([email protected]) added native attachment /tmp/AIXOS06698101/systemd_229.patch on 2017-01-07 20:22:29 Confirmed that the following fix is part of 232 present in zesty. Marking as Fix Released for devel series. Accepted systemd into yakkety-proposed. The package will build now and be available at https://launchpad.net/ubuntu/+source/systemd/231-9ubuntu4 in a few hours, and then in the -proposed repository. If this package fixes the bug for you, please add a comment to this bug, mentioning the version of the package you tested, and change the tag from verification-needed to verification-done. If it does not fix the bug for you, please add a comment stating that, and change the tag to verification-failed. In either case, details of your testing will help us make a better decision. systemd-231-9ubuntu4 looks good for yakkety. It appears that there are other changes since user-0.slice was no longer present, but the parent pids.max is now set to "max": root@kwr-yakkety:~# cat /sys/fs/cgroup/pids/user.slice/user-0.slice/pids.max cat: /sys/fs/cgroup/pids/user.slice/user-0.slice/pids.max: No such file or directory root@kwr-yakkety:~# cat /sys/fs/cgroup/pids/user.slice/pids.max max We are now just waiting on xenial for closure.
