Any idea what could be causing this?

  • Hi Matt and welcome to the UTM Community!

    What do you see in the log just before this starts appearing?  What do you see in the UTM logs when this happens?

    How long does STAS continue working after a restart?

    Do the Windows server and the UTM both get the time from the same source?

    Cheers - Bob
