Hello Amira,

Generally, every clustered machine establishes an SSH connection to all other machines in the cluster. Clustered machines ping each other every 2 minutes to verify the connectivity. If a machine does not receive a response form the other end within 2 minutes, it closes the connection and establishes a new one.

If this is a one time alert then the probable cause is most likely some network latency. 

You can review the current cluster connectivity via the CLI by using the following commands : clusterconfig --> connstatus. You can also perform telnet tests from one ESA to another via port 22 or 2222 (whichever the cluster is using) to verify current connectivity.

Thanks!
