Post journalctl -xe and systemctl status httpd.service -l command output in question. — Pandurang

Stop the Apache httpd service and check semaphore usage owned by the apache user.

ipcs -s

Execute the following command to clear semaphore used by Apache user.

ipcs -s | awk -v user=apache '$3==user {system("ipcrm -s "$2)}'
