Solusinya
Ini karena pengontrol cgroup PID diperkenalkan dengan SUSE12.
Dari bagian "Dukungan untuk PID cgroup Controller" di https://www.suse.com/releasenotes/x86_64/SUSE-SLES/12-SP2/#fate-320358"Untuk mengontrol pengaturan TasksMax=default untuk layanan dan cakupan yang berjalan di sistem, gunakan pengaturan system.conf DefaultTasksMax=. Pengaturan ini default ke 512, yang berarti layanan yang tidak dikonfigurasi secara eksplisit jika tidak hanya akan dapat membuat 512 proses atau utas maksimum.
Untuk layanan thread-atau proses-berat, Anda mungkin perlu menetapkan nilai TasksMax yang lebih tinggi. Dalam kasus seperti itu, atur TasksMax langsung di file unit tertentu. Pilih nilai numerik atau bahkan tak terhingga."
Dari SLES12 dan seterusnya, systemd digunakan sebagai ganti initd dan server OHASD hanya diperbolehkan untuk membuka maksimal 512 tugas. Konfigurasikan nilai DefaultTasksMax ke 65535 dalam file /etc/systemd/system.conf atau atur nilai TasksMax dengan benar untuk layanan ohasd systemd.
Misalnya:
# 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
