Yesterday in the middle of the day...all of our phones in one location dropped and displayed "Waiting for Ack..." We using 3300 and 5330 phone
In the logs I see: Heartbeat Server - ICP lost contact with xxx.xxx.xxx.xxx , network driver cluster pool free: 6068 and low water mark: 5961
I rebooted the system and the phones came back. If I look at the phone inventory I now see In Service
Registration Reason Set Error: ACK expiry . We don't have anything special setup...no MBG or anything like that.
Any ideas what the issue here is and what caused the waiting for ACK? I was thinking originally a DHCP issue, but not sure.
Thanks for the help! I did a search but it didn't really apply to our setup.

Were phones the only thing to go down?

Were phones the only thing to go down?
Yes...phones were the only thing to go down. Several weeks before this issue we swapped out the controller as we had the MIPS processor issue. Tech took the drive out and put in a new controller. We did update the bootrom as well, so I don't think it had anything to do with the swap.
Strange issue

Do the phones get their DHCP from the ICP or another source? Maybe the switch forgot the DHCP helper for the voice network? If all the phones requested renewal at the same, or roughly the same, time I could see something like that happening.

Actually I'm not sure my last reply makes sense if rebooting the 3300 fixed it.

What do the logs show you right before "ICP Lost contact" messages? Anything indicating network connectivity issues?
