    I'm also getting this in my logs.
    Jesterday I upgraded from 6.0.6 NE to 6.0.12 NE on SLES 10 x86...
    Here' link for more info about jetty JVM NIO bug
    Seems to me like a jvm bug workaround...
    My question is, does this influences on performance? The reason for upgrade was slow responsiveness from mail server.
    Thanks, regards

    This messages are nothing you have to worry about. As Aleks wrote, this is caused by Jetty workarounds implemented to deal with some JAVA JVM NIO Bugs: Jetty/Feature/JVM NIO Bug - Eclipsepedia until the bugs are being fixed.

    This doesn't affect performance in any way a user might notice.
