    I see... any specific exception? Do you have a stack trace? It will be
    helpful to pinpoint the problem.

    Another question - is it possible that while Tomcat is running, MySQL is
    restarted independently from Tomcat?

    This seems a likely cause of this problem. Of course this may need a better
    handling in Cayenne internal connection pool and I really need to do some
    testing of this scenario.

    Cheers,
