Because I seem to have many retransmits of accounting packets, of which I
didn't find the cause yet, there are a lot of errors returning from the SQL
table (already inserted). Because of this, it seems that radiator is losing
performance.
When I remove those UNIQUE indeces, the TIME_WAIT problem on my radius
server seems fixed.
Does radiator "back off" for a while, after getting back an error from his
back-end database? Or what else might cause these errors, to have a direct
impact on radiator performance?

PS: TIME_WAIT problem has been fixed, as said, by removing UNIQUE indeces,
from the accounting table.
