Description
When starting the EMS server using RHEL service, it will not pick up the limits value set in limits.conf file or ulimit command. As the limits.conf is read by pam_limits module during login sessions. The login session can be by ssh or through terminal. And ulimit command is used to set the limits of the shell. Only the process which gets spawned from the shell can get the value set by ulimit command.
Environment
Resolution
Please add LimitNOFILE=value to set the FD for the EMS server started by the RHEL service. For example:
