The system is an upgraded 6.0 with the latest patches. We have always seen high usage on the CPU but lately it has been tame. Most Sets are IP and there is 32 of those with i think 5 Digital sets. The system is using a PRI for lines and when I get the error eventually my Find Me/Follow Me stops working, and in the past so did the Conference Bridge. Both of these things are crucial to the client of course that's when a call comes to me, and that's when I have to reboot the system. After the reboot everything works fine for a while, but recently the reboots are only fixing the issue for a short period of time, before it was months now i am lucky if i get a week out of one. Anybody out there seen this issue and if so what was the fix?
