Hi,

first sorry for my english.

last week i had cucm version 6.1.5 on mcs 7845 h1 and unity connection on mcs 7845 h2.  all work fine.

last weekend i upgrade my cucm to version 8.5.1 and i backup the publisher to restore on UCS R210-2121605 (on virtual machine).

i keep the unity connection server on the MCS server.

yesterday on load (many call in same time) the system coming very slow to answer every 20-25 minutes for 5 minutes and unity come back correctly after 5 minutes.

last night i changed server.  i toke backup of my mcs to restore on new install of UCS (new installation of unity connection).

during the night all my setup (cucm and unity) work fine.

this morning i have the same trouble.  each 20-25 minutes i can't reach voicemail pilot. 

I don't have any rtmt error,  the cpu and memory of unity and cucm are normal (around 10%).

this is the solutoin

my unity was registred on call manager publisher on IP 10.64.1.10/255.255.255.0 gw 10.64.1.1 and my subscriber 10.64.1.140/255.255.255.0 gw 10.64.1.129.

my unity connection have ip adress: 10.64.1.170/255.255.255.0 gw 10.64.1.129.

i have i trunck between the 2 switchs with 3 vlan inside.  the call managers and unity are in the same vlan but my cucm publisher are in a different building.

i don't know why, but i registred unity connection on subscriber and it's stop freeze each 20 minutes.

the theory said my cucm cluster and my uinty are in the same network (it's work fine before my upgrade) suppose to work and the same network and for communicate outside this network  each server toke how gateway.  but not each 20 minutes
