The process vyprvpnservice (current version) is using 100% of one processor on my iMac (10.11.1). The problem appears each morning after the system was idle all night. I kill the process, terminate vyprvpn and restart vyprvpn and everything is fine for the day again. I get all VPN connection I want. Until next morning when the service using 100% of one processor again. The service is still sleeping at about 2am when I go to bed.
I made one change to my system recently. The default user got the admin privilege removed. Another dedicated user is used for the admin privilege. I need to enter the admin user with password to terminate the service in the morning from the default user as expected.
