Hi, We are running freeradius 3.0.19 on RedHat 7.6 and trying to run as a daemon via 'systemctl start freeradiusd.service'. But executable starts and it is killed immediately. We have the following entries in the log /var/log/freeradius/radius.log. Does anyone know why is it getting a signal to terminate? Any help is appreciated. Upon checking the process with 'strace' output, it shows that it is terminated with a SIGTERM signal.

We renamed the binary as freeradiusd from radiusd as per our naming convention. As per http://lists.freeradius.org/pipermail/freeradius-users/2018-May/091636.html, the warnings are due to Redhat switching the library to NSS from OpenSSL in 7.6. Could the SIGTERM that we receive be because of the warning messages below?
