looks like the network connectivity issue.

from all server perfrom below commands

utils diagnose test

utils network connectivity

utils dbreplication runtimestate

above the commands output will give all the information you need to fix replication issue.

Hi Vipul

- utils diagnose test

Command not exist

- utils network connectivity

admin:utils network connectivity

This command can take up to 3 minutes to complete.

Continue (y/n)?y

Running test, please wait ...

............................................................Network connectivity test timed out.

Cluster Manager may be in a bad state.

Use the command 'utils service restart' to restart Cluster Manager

admin:

- Ping : There are ping both directions.

- RTMT : Replication status PUB = 2

Replication status SUB = 0

Aby idea?

TIA

utils dbreplication clusterreset all command should follow by cluster reboot.

if you dn want to reboot the cluster, you run the command

utils dbreplication reset all

thanks,

Dear Vipul

I opened a case in Cisco TAC. Took the case your coworker John-Paul.

Yesterday at night, I performed a reboot the cluster and then, all servers have a replication count of 348 and all servers have a good replication status.

The customer wants to know why this problem occurred. Please, if you have an idea, could you tell me what are the reasons that could cause this problem?.

TIA.
