Hi everyone,
we are having an issue on our FreeRadius setup where our redundant servers will
maybe once, twice a day create duplicate accounting entries.
I have switched the servers to debug for a full day and caught one of these
incidents in the log file, see attached.
The strange thing is it only happens maybe once a day, regardless of realm or
user, and the other couple of hundred accounting requests are fine.
Can anyone see why this particular one would bounce back and forth?
Our setup consists of two virtually identical FreeRadius2 servers, each with
their own mySQL database, so each of them is capable of doing Auth and Acct,
and proxies Acct to the other one.
Also I changed the acct_update_alt query to write to a failover table since I
thought this was the alt query being triggered, but this does not make a
difference. Still duplicates in radacct table.
Thanks!
Marius
