The logrotate configuration snippet is:

# cat /etc/logrotate.d/omniNames
/var/log/omniORB/*.log {
       weekly
       rotate 10
       copytruncate
       delaycompress
       compress
       notifempty
       missingok
       postrotate
          /bin/kill -USR1 `cat /var/run/omniORB/omniORB.pid 2>/dev/null` 2> /dev/null|| true
       endscript
}

Firstly, sending SIGUSR1 immediately terminates the daemon:

# systemctl kill --signal=USR1 --kill-who=main omniNames.service
# systemctl status omniNames.service
× omniNames.service - OmniORB Naming Service
     Loaded: loaded (/usr/lib/systemd/system/omniNames.service; disabled; preset: disabled)

Jun 06 15:30:20 fedora systemd[1]: Started omniNames.service - OmniORB Naming Service.
Jun 06 16:08:22 fedora systemd[1]: omniNames.service: Sent signal SIGUSR1 to main process 3690 (omniNames) on client request.
Jun 06 16:08:22 fedora systemd[1]: omniNames.service: Main process exited, code=killed, status=10/USR1
Jun 06 16:08:22 fedora systemd[1]: omniNames.service: Failed with result 'signal'.

Secondly, the PID file no longer exists since the initscript was retired:

# systemctl restart omniNames.service
# cat /var/run/omniORB/omniORB.pid
cat: /var/run/omniORB/omniORB.pid: No such file or directory

Lastly, the logrotate configuration snippet uses copytruncate, which always keeps the same log file in place, making it unnecessary for the daemon to reopen the file. Therefore, please remove this part:

postrotate
  /bin/kill -USR1 `cat /var/run/omniORB/omniORB.pid 2>/dev/null` 2> /dev/null|| true
endscript

Reproducible: Always
