Rhino 5 & 6 freezing randomly

My system info:
I am using a network server and network license.

It freezes every 5 minutes or so. sometimes it freezes after immediately I made the first command after opening. The situation gets better after I restart. But after like 20 minutes, it starts to freeze constantly again.
