    Default AJP - Database Problem

    Hello!

    This morning i got an error with my open-xchange. In the open-xchange.log was this error:

    Code:

    I don't know the problem, but after a restart the system is working.

    I also found a second problem.

    What is the problem? Is there something wrong with my database-connection? Here my configdb.properties:

    Code:

    Hi,

    those are no severe errors. The first informs, that an action did run for more than 1 monute. The second informs, that a database access took longer than 2 seconds. These are pretty common status messages.

    Greetings
