[jbpm-users] [JBoss jBPM] - jbpm persistance fails after running for a while

Hi, I've got a problem difficult to trace. My application works well, but after a while (I leave in the evening and come back the day after), the persistance is over. I'm running jBPM 3.3.1GA and MySQL 5.1.11, with the JDBC connector mysql-connector-java-5.1.7 here is the log I get: http://pastebin.com/m1c2c39e9 Lika I said, it's hard to debug because it's happening only after a while. Moreover, the MySQL server is still active and running (I also have a login process in my application, and it still works), so I think that the problem comes form jBPM. Here is an example of my code that uses jBPM API, in case of the use of persistance is wrong : http://pastebin.com/m4e20e430 Do you see something wrong?
