Hi,
I know that this problem is quite well-known but also with values that seems to me correct I've the problem.
I've a app running on tomcat 24h a days. It's a system that responds to many xml/rpc requests and make queries to the db.

After some hours of usage I've this error:

Code:

When the app freeze, "SHOW PROCESSLIST" show an acceptable number of processes, much less than 300 indicated in the configuration file.

Any ideas to solve the problem?

Thanks in advance
