Hello,
2 Subscribers are reaching 90% CPU Usage, when I looked in the RTMT I saw that the Database Layer Monitor (DBmon) Process got 49% CPU usage on Sub1 and 45% CPU usage on Sub2. I ran utils DBreplication runtimestate command and seems like there is no problem with the replication between the 3 servers (Pub, Sub1, Sub2).
I pulled out Database Layer Monitor process Logs from the RTMT and will post the logs here, the Log doesn't contain too much Information, if there are other logs I should be looking at - would be grateful for any suggestions.
Thanks in advance.

Hi Nathan,
Yes, also this is not a new environment. these servers are up and functioning for at least 2 years, never encountered this issue before.

Hi Nathan,
There is enough free space on the partitions, total phone count registered is 3600, about 1000 to each server when each server can deal with up to 7500 phones.

Hi again Mohammed and thank you,
The "Table out-of-sync detection" service is off, it was never on as far as I know.
I have around 3600 registered phones.

Restart of the Cisco Database Layer Monitor service resolved the issue, Cisco Tac was opened, trying to figure out the root cause of this event.
