Hi,
We are having an issue where, in some sessions, an Authentication
Request is sent successfully (and inserted into RADPOSTAUTH table), but
the Accounting Start Query is never run/received.
Subsequently, Accounting Update Queries come through, but fail due to
the fact that a relevant RADACCT session has not been inserted to begin
with.
It only happens in a small amount of cases, < 1% of sessions, but
nonetheless opens us to loss of data that is not being billed for properly.
Is this a known issue? Is there a workaround? We're looking at changing
the Acct Update Query to insert a new session if it cannot find an
existing one.
Any help will be appreciated.
You should never rely on receiving accounting queries.
They are UDP and easily go missing.
You could even receive duplicates (e.g. two start packets).
What I have done (pseudo code):
if (Start)
{
Try to insert Session
If already exists, update
}
elseif (Interim)
{
Try to update Session
If not exist, insert
}
elsif (Stop)
{
Try to update Session
If not exist, insert
}
