Hello! Can anyone confirm this? Is further information needed to investigate? Thanks, JB JB wrote:

Hi!

We're currently testing FR 3.0.1 with RadSec and we're seeing crashes when we turn off an access point. In the log below you can see that the access point sends an accounting stop request before it powers down. FR crashes after closing the socket. I also pasted the GDB stack trace below.

BTW, we're also seeing these warnings a lot and we're not sure what they mean or how to prevent them:

Debug: (19) Writing to socket 12 Debug: (19) Finished request 19. Debug: Thread 1 waiting to be assigned a request WARNING: WARNING: Socket was closed while processing request 19: Stopping it. Debug: (19) Cleaning up request packet ID 73 with timestamp +1053 Debug: Waking up in 1.1 seconds.

Cheers, JB
