ZYWALL USG 20

Hi, our usg 20 is rebooting every 15-20mins with the error ctipd.bin is dead. I have updated the firmware to latest 330BDQ9ITS-WK48-r74988 and checked that content filtering is turned off. But issue still persists. I am experiencing this on both usg 20 routers that we have. Are there any other things we can do?

    It might be a WAN attack as the USG20 is old no longer gets fixes.

    Unplug the WAN interface. Then ping for 25 minutes the device, waiting for any downtime.

    If this happens, might be an issue of the power adapter. Consider that to 12v 2A might work any other power adapter.

    Does this ZyWALL USG 20 still have Anti-Spam license? Could you give me the serial number and MAC address of this device in private message? Thanks!
