Zywall USG 50 / HIGH CPU / REBOOTING

SecureU

alert messages keeps showing in the firewall logs displaying the following.

ctipd.bin is dead at (date/time)

- App watch dog recover ctipd.bin dead

 - App watch dog stop to recover ctipd.bin. Daemon state: dead

- ctipd.bin is dead at (date/time)

- diagnostic-info is collecting now. Wait it to complete 

I noticed that, after these alerts, CPU usage keeps growing up to almost 100%, then the device reboots

I have tried, all verions of firmware and the issues is not resolving. I was using the latest 3.30BDS.9 firmware, ive tried rolling back to 3.30BDS8 & 7. No success. Please assist.
