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 ** Attachment added: "debdiff between systemd_229-4ubuntu14 and test build systemd_229-4ubuntu15" https://bugs.launchpad.net/bugs/1651518/+attachment/4801481/+files/systemd_infinity.debdiff -- 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/1651518 Title: systemd/logind parsing problem: HTX exercisers stopped on error: rc 11, errno 11 from main(): pthread_create Status in systemd package in Ubuntu: New Status in systemd source package in Xenial: New Status in systemd source package in Yakkety: New Bug description: == Comment: #1 - Application Cdeadmin <cdead...@us.ibm.com> - 2016-12-19 04:15:10 == Configuration: IBM 8001-22C (S822LC), LSI SAS adapters, SMC 4U90 disk drawers, HDD (180) 7.3TB Problem: HTX exercisers stopped on error, with HTX log showing "rc 11, errno 11 from main(): pthread_create" htxubuntu-425 lpar: busybee.aus.stglabs.ibm.com (root/ lab passwd) root@busybee:~# uname -a Linux busybee 4.4.0-51-generic #72-Ubuntu SMP Thu Nov 24 18:27:59 UTC 2016 ppc64le ppc64le ppc64le GNU/Linux root@busybee:~# cat /tmp/htxerr /dev/sdh Dec 12 23:52:42 2016 err=0000000b sev=1 hxestorage rc 11, errno 11 from main(): pthread_create /dev/sdh Dec 12 23:52:42 2016 err=0000000b sev=1 hxestorage Hardware Exerciser stopped on an error /dev/sdao Dec 12 23:52:42 2016 err=0000000b sev=1 hxestorage rc 11, errno 11 from main(): pthread_create /dev/sdao Dec 12 23:52:42 2016 err=0000000b sev=1 hxestorage Hardware Exerciser stopped on an error /dev/sddx Dec 12 23:52:42 2016 err=0000000b sev=1 hxestorage rc 11, errno 11 from main(): pthread_create /dev/sddx Dec 12 23:52:42 2016 err=0000000b sev=1 hxestorage Hardware Exerciser stopped on an error /dev/sdcz Dec 12 23:52:42 2016 err=0000000b sev=1 hxestorage rc 11, errno 11 from main(): pthread_create /dev/sdcz Dec 12 23:52:42 2016 err=0000000b sev=1 hxestorage Hardware Exerciser stopped on an error /dev/sddp Dec 12 23:52:42 2016 err=0000000b sev=1 hxestorage rc 11, errno 11 from main(): pthread_create /dev/sddp Dec 12 23:52:42 2016 err=0000000b sev=1 hxestorage Hardware Exerciser stopped on an error No errors logged in syslog after starting HTX: ==== State: Open by: asperez on 16 December 2016 10:28:02 ==== This error recreated on the smaller 1U Open Power system with the same smaller 1-adapter/1-4U90 drawer/90 HDD.

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. Rudd <ru...@us.ibm.com> - 2016-12-19 17:34:27 == 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 == Comment: #4 - Kevin W. Rudd - 2016-12-20 10:25:09 == Canonical, This issue appears to map to the following systemd bug and patch: https://github.com/systemd/systemd/issues/3833 https://github.com/systemd/systemd/commit/f50582649f8eee73f59aff95fadd9a963ed4ffea This patch appears to be included in debian/232-7, but is missing in the xenial and yakkety versions.
