Sometimes, Essbase services are not using configured system limits.

Workaround: Access the file sudo vi /etc/systemd/service/essbase_domain-nodemanager.service and edit it as follows:

1. Add the following lines to the [Service] section of the file:

   LimitNPROC=32768
   LimitCORE=infinity
   LimitDATA=infinity
   LimitAS=infinity
   LimitNOFILE=16384:65536

2. You must restart the processes as follows:
   1. Stop the instance:

      $DOMAIN_HOME/esstools/bin/stop.sh

      where $DOMAIN_HOME is pointing to /u01/config/domains/essbase_domain/.

   2. Restart node manager service:

      sudo systemctl restart essbase_domain-nodemanager

   3. Start the domain:

      $DOMAIN_HOME/esstools/bin/start.sh
