Loosing and not recreating MySQL database session

[phaethon]

I have installed Alfresco with JDK 1.5.0, MySQL 4.1 working on FreeBSD 6.0. After an hour or somewhat more after starting the service if no activity is performed seems that database connection iis lost and new one is not created. While I actively work with Alfresco everything is ok.
MySQL is on the same server so there are no network connectivity issues.
I have tried with AutoReconnect=true, but nothing changed.
I also tried org.gjt.mm.mysql and com.mysql driver versions with the same results.

This is the message I get:
