[Help-gnu-radius] Problem with too many SQL connections

[Norman Schmidt Jr]

Hello!
I'm using 0.96.3 and getting plenty of "too many SQL connections open" 
errors on radius.log.
I'm using MySQL 3.23.51, and I have already raised some MySQL parameters 
(max_connections to 500 and max_delayed_threads to 100) trying to get 
rid of this, but with no success, the errors are still ocurring.
Any tips on this? Slow hardware? The setup is running in a Dell 
Poweredge 600, Celeron Coppermine 1.1 Ghz with 512Mb RAM. This machine 
runs only GNURadius 0.96.3 and MySQL 3.23.51. Only Radius accounting is 
going to MySQL, authentication is still done from Linux password file. 
There's about 3200 accounts in the password file, and this machine 
authenticates about 4000-7000 logins a day.
Following is a snip of the radius.log.
Regards,
Norman
