Hi,
I did upgrade from V6.37.1 to V642.2 and it worked.
But after some time i noticed that the IPV6 was disabled.
I enabled IPV6 rebooted the server and it continued rebooting until I power off the server, disconnected all ethernet interfaces, power on server, wait it go to running state, connected one by one the ethernet interfaces.
But if the server reboot i need do the steps below again.
Anyone reported it?

Thanks in advanced.

Check up CPU usage when IPV6 is enabled

CPU usage normal, the issue occurred only on boot.
