This is due the PIDs cgroup controller introduced with SUSE12. 这是由于 SUSE12 附带的 PIDs cgroup 控制器
From the "Support for PIDs cgroup Controller" section on https://www.suse.com/releasenotes/x86_64/SUSE-SLES/12-SP2/#fate-320358
"To control the default TasksMax= setting for services and scopes running on the system, use the system.conf setting DefaultTasksMax=. This setting defaults to 512, which means services that are not explicitly configured otherwise will only be able to create 512 processes or threads at maximum.
要控制TasksMax的默认值，请使用system.conf设置DefaultTasksMax。此设置默认为512，这意味着未明确配置的服务最多只能创建512个进程或线程。
For thread- or process-heavy services, you may need to set a higher TasksMax value. In such cases, set TasksMax directly in the specific unit files. Either choose a numeric value or even infinity."
对于大量使用线程或进程的服务，您可能需要设置更高的TasksMax值。 在这种情况下，请直接在特定 unit files 中设置 TasksMax。 选择一个数字值，甚至选择infinity。”
From SLES12 onwards, systemd is used instead of initd and the OHASD server is only allowed to open a maximum of 512 tasks.
从SLES12开始，使用systemd代替initd，并且只允许OHASD服务器打开最多512个任务。
Configure the value of DefaultTasksMax to 65535 in the file /etc/systemd/system.conf or or set the TasksMax value properly for the ohasd systemd service.
在文件 /etc/systemd/system.conf 中将 DefaultTasksMax 的值配置为65535，或者为 ohasd systemd 服务正确设置TasksMax值。
For example:
# cat /etc/systemd/system/ohasd.service.d/lunar.conf [Service] TasksMax=16384 <<<<<<<<<<< # systemctl status ohasd ● ohasd.service - LSB: Start and Stop Oracle High Availability Service Loaded: loaded (/etc/init.d/ohasd; bad; vendor preset: disabled) Drop-In: /etc/systemd/system/ohasd.service.d └─lunar.conf Active: active (exited) since Mon 2017-11-13 14:29:23 CET; 3h 5min ago Docs: man:systemd-sysv-generator(8) Process: 4876 ExecStart=/etc/init.d/ohasd start (code=exited, status=0/SUCCESS) Tasks: 612 (limit: 16384) <<<<<<=================== here was the limit with 512
