Dial up error and freeraius is down

[Robin]

Hi,

Thanks your suggestion.

I will clean records from radacct and check my reporting system if it effect
freeradius operations.

I don't understand what you mean by "my freeradius for some reason has
slowed due to response behind time", but like Alan said, the cause of that
log is usually because your backend (mysql?) didn't return timely response
which cause the NAS to re-send the request. When FR received the duplicate
request, it discards the request since it detects it's still processing the
old one.

Things you might want to check:
- is there a bottleneck in your MySQL? Sometimes a reporting query locks the
tables so other queries (like select/insert from FR) can't be processed.
- how big is your radacct table? When unmaintained, it can have millions of
records, and some FR feature (like sqlcounter, or simultaneous use checking)
reads entries in radacct
- how efficient is your sql schema? Having lots of indexes can speed up
certain select queries, but it can kill write
(insert/update/delete) performance.

In other words, get a DBA, check your MySQL setup.
