Strange Analysis Plane CPU usage after upgrade to Version 13.0 with Hot-fix( 12.1.2 )

Additional comments : 1- when I deactivate DoS profile from Virtual servers in Version 13 ( Hotfix2 ) , the CPU problem will be solved but the CPU usage will raise to 100 % as soon as I assign DoS profile to virtual servers . 2- I tried to use default DoS profile and also set all the DoS Device configuration settings to Auto Threshold but still the CPU was high which means the problem is not for DoS configuration 3- Something is wrong with MySQL/AVR since avrd command is occupying 100 % of CPU all the time 4- Finally I have rolled back to Version 13 and there is no problem with the CPU and everything is fine in this version Now I want to know what is the reason for this issue in Hot Fix 2
