According to Oracle, these warning messages are because of F5 configuration.

    Hi, what is the monitor applied to pool?

     

    It seems it’s a tcp monitor with 5 sec interval which close the connection when it success...

    Hi

     

    your application server seems Oracle.

     

    I recommend using ORACLE monitor.

     

    Oracle monitor didn`t close session that is proper than TCP monitor(close session).
