random reboots and Cisco AnyConnect

I would appreciate your help with the following problem. It seems that AnyConnect Client software 3.1.100.10 that my university uses for VPN causes random reboots on my MacBook Pro running Sierra OS. Here's a few lines from the system.log just prior to a recent reboot:

Feb 5 15:15:26 VMrMBP17 com.apple.xpc.launchd[1] (com.apple.xpc.launchd.domain.system): System reboot initiated by: eoshostd.192<-launchd.1

In addition to reboots, I'm also experiencing problems when switching user accounts: the system sometimes would just logout all users from the Mac. The system.log file is filled with VPN error messages. Please, see below. I'm wondering if it's a know problem and if there is a solution.

Thanks
