I'm not sure when its began but everything was okay about 1 mounth ago.
When I log in, Firewall starts to consume CPU and RAM.
It rises to 1.5 GB in about 1-2 minutes.

During this time I can not access internet sites until the CPU usage is over.

When the CPU usage is over, the memory drops to 800MB and stays there.

The strange thing is this process not using any disk I/O.
I don't know how its using memory without Disk usage.

MY OS: 1607 Enterprise (up to date)

I couldn't find any solution and i can't see wtf firewall doing...
If i catch some log i will found solution..
