Configuring Default Thread Limits Value for SUSE Linux

If you are on SUSE Linux Enterprise Server 12 SP2 or later, or SUSE Linux Enterprise Server 15 or later, then set the DefaultTasksMax parameter value to 65535.

Increase the default thread limits, DefaultTasksMax value from 512 to 65535 to avoid running into service failures.

1. View the contents of /etc/systemd/system.conf to know the current DefaultTasksMax value. Alternatively, run the following command:

   $ systemctl show --property DefaultTasksMax

2. If your DefaultTasksMax value is not 65535, then uncomment the line in /etc/systemd/system.conf and set the value to 65535.
3. To enable the new settings, reboot your system or run the following command:

   $ systemctl daemon-reload
