couldn't reconnect to the home server

[Prem Khanal]

Hi All,

I have configured freeradius 3.0.19 as proxy server which forwards radius
accounting packets to specific home servers based on NAS IP. The problem I
am having is once the connectivity to the home server goes down, the radius
proxy can not reestablish the connection to the home server.
If I delete detail and detail.work files and restart the freeradius service
everything starts working well. I was wondering if I am missing something
in configuration that is causing this problem.

Here is the log
