Hi Alan,

We have made some more progress today. We have tried using the v3.0.x branch and got similar results which led us to try further tests.

Because we see the debug output saying the remote server has stopped responding we tried sending the detail file packets back to our self on the local machine. This was a total success. Then suspecting that the network between the machines was a contributing factor, we tried another "closer" machine on the same subnet and this was also successful.

Reverting back to the original remote machine shows the problem still exists on both 3.0.3 and v3.0.x and hopefully the debug extract below shows what happens. Once the Status-Server message has been answered the detail processing on the sending server never re-starts even though the remote server is marked as alive. The detail.work remains in the radacct folder and any new files appearing there are also ignored. It feels like even if a remote server or network is slow or un-reliable, Freeradius should be able to recover and continue processing the detail file.
