I had to raise them because freeradius daemon was complaining to the log about 
problems with opening some files. Either the mysql socket or the detail log 
file. The server is pretty loaded (up to1.600 req/s in peaks). I have about 
600 connection to the DB. It looks that problem appeares when the rate goes 
over 1.100 req/s. Of course the bottleneck is the DB. On the other hand there 
is not too much to do on the DB side. Having ~1 million of sessions in a 
InnoDB table with the rates mentioned above is not easy. Nevertheless I am 
trying to tune the best config for this purpose...
