I use the Sophos Single Sign-On Client (SSO) the first one in Client downloads page.
The thing happens at morning as i notice my internet connection in my desktop lost constantly, then i check the xg find there is high cpu usage with little traffic. Using top i find a "worker" process constantly running 100% (suppose it's single threaded), and "access_server" "login_user" "logout_user" apear time to time with high cpu usage. This brings me the the authentication log where i find the logs below, which is apearantly unnormal.

I manually stop all of the SSO Client and CPU instantly went back to normal (mostly idle).
So far i have tried reboot every thing around it and itself. I also have tried to restore a know good config backup a month ago. Rollback to the 16.01.3 MR-2. All of them didn't solve the problem.
