    Hi, disable Session Limit or change the threshold.

    Hi @RGMConsulting,

    From your screenshot, client 10.9.1.59 created many UDP sessions with different IP addresses. Is it a server? If yes, you can go to Site-wide > Configure > Security gateway > Traffic shaping > Session Control to change the number of Session per Host.

    If it is just a PC, you will need to check whether it is infected.
