Hello Alan, thanks for your reply. I have built the 3.0.18 version and the issue seems to have gone away. Thanks a lot for the help!

After running FreeRADIUS for a while (3.0.17 built from GitHub release page), I noticed that the server ends up in a loop writing out following messages:

Fri Aug 17 17:33:05 2018 : Debug: (0) Reading from socket 33 Fri Aug 17 17:33:05 2018 : Debug: (0) Reading pending buffered data Fri Aug 17 17:33:05 2018 : Debug: (0) Failed writing 0 bytes to SSL BIO: -1 Fri Aug 17 17:33:05 2018 : Debug: (0) Application data status 4

I have RadSec configured for the RADIUS (TLS tunnel). When I was running 3.0.15 version, this wasn't happening. Any idea what could be happening?

Upgrade to the v3.0.x branch. We put some fixes in after 3.0.17 was released. Alan DeKok.
