CM600 Rebooting
Hello,
We have a CM600 modem serving our company buildilng (about 20 active workstations, 1 public web server). The modem seems to be rebooting several times per day, which brings down all internet and phone service in the building. I've pasted the logs below, we had reboots shortly after 10:40, shortly before 11:00, and shortly before 11:05.
