I receive the same alerts from my SMA M670 who is at the version 10.0.0-055 since I upgraded my 2 C370 to the version 9.7.2-047.
No more message tracking, message reporting on my M670.
The Critical message is:
TRANSFER: The following centralized services and hosts have been unreachable for file transfer:
Centralized Service "Message Tracking" has not connected to host 10.177.30.84 in 133 minutes.
Centralized Service "Message Tracking" has not connected to host 10.177.30.86 in 133 minutes.

In my case, the SMA is in version 10.0.0-096. Following Cisco investigation, it seems the appliance is affected by a SNMP bug. CPU usage goes very high and the SMA becomes slow. Because of this slowness, there is a connection timeout between the ESA and the SMA. After x timeouts, the ESA is blocking internally the IP address of the SMA. See bug-id CSCvb10032.
A fixed release should be available soon. The workaround is to disable SNMP on the SMA. For the moment, I upgraded to 10.1.0-037 (not listed as affected) and still have the SNMP enabled.
I will continue to monitor and give a feedback here.
The version 10.1.0-037 has been added to the fixed releases list for the SMA. I confirm it fixes the issue. No need to disable SNMP.
You may have to open a service request in case of ESA has internally blocked the IP address of the SMA, after several download failed. The TAC will re-authorize transfer.
Hope it can help some of you.
