Description

SLES 12.x uses Systemd v228 which imposes a 512 process/thread limit for processes started by ambari-agent if both ambari-agent and the process runs as root.

The solution should be a systemd service unit file that sets TasksMax=infinity for ambari-agent to overcome this limitation. TasksMax is a parallel mechanism to process limits, so limits will still apply.

The ambari-agent rpm must be build with -P suse12 in order to include the service file in the rpm.
