Weird TLS behavior in FreeRADIUS

[Jan Hajek]

Hey everyone,

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?

Thanks a lot,
Jan
