Inferior 1 [process 12145] will be detached. Not sure if this is related but after restarting httpd the avahi-daemon starts using CPU: PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND 794 avahi 20 0 16336 13120 4220 R 90.0 0.0 5:44.02 avahi-daemon spams the logs with: Jan 14 09:51:23 storm avahi-daemon[794]: Too many objects for client ':1.20169', client request failed. then eventually settles down. Do you have mod_ssl installed? If so please check for log message AH02042 in (e.g.) /var/log/httpd/ssl_error_log, could be a duplicate of bug 1664414. openssl version OpenSSL 1.1.1a FIPS 20 Nov 2018 httpd -t -D DUMP_MODULES | grep ssl ssl_module (shared) And yes a few AH02042 and if it helps to know these are from the Qualys vulnerability scanner.
