Re: [Help-gnu-radius] GNU Radius and 'NAS has wrong ID' problem

There are two possible cases:

1) logout: entry for NAS %s port %d has wrong ID (expected %s found %s)

Somehow the start accounting record of the next session for this
NAS/port combination has been processed before the stop accounting
record reached the server. Usually this means the original start
record was lost, and the NAS retransmitted it later, but by the
time the record was received, the entry was already marked as
being used by another session. 

2) login: entry for NAS %s port %d wrong order

While writing a start entry, radiusd discovered that this NAS/port
combination is already marked with stop for the same session id.
This means that the stop record reached radius server before the
start record (possibly due to network issues or high server load).
Usually the corresponding session has zero Acct-Session-Time
attribute.

Which one do you see in your logs?
