Hi List syslog-ng 3.5.6 fails to start up on a newly installed CentOS 7 server: Environment details: OS: 3.10.0-327.10.1.el7.x86_64 Distro: CentOS Linux release 7.2.1511 (Core) Syslog-ng: syslog-ng-3.5.6-3.el7.x86_64 I'm doing a fresh install on CentOS linux and installing syslog ng from epel-release repo. syslog-ng fails to start up via systemd as follows: systemctl restart syslog-ng Job for syslog-ng.service failed because a fatal signal was delivered to the control process. See "systemctl status syslog-ng.service" and "journalctl -xe" for details. Looking at journalctl -xe output: - Unit syslog-ng.service has failed. -- -- The result is failed.
