Hi,

we currently have sometimes a issue with radsecproxy.
The proxy logs the following and CPU of the VPS increases to 100% and logs the following in loop(thousand's of entries in a few seconds.):

Thu Nov 24 09:43:25 2022: sslreadtimeout: SSL: error:0A000197:SSL routines::shutdown while in init                                                                                                                                       
Thu Nov 24 09:43:25 2022: sslreadtimeout: connection lost: No error information     

I'm currently not able to reproduce it reliable and also analysing the traffic to see what it causes. But nonetheless the process shouldn't fall in such stage.

config:


ListenUDP       *:1812
