I’m having same issue:

CLIENT: 3.0.2 REDIS: 5.0.3

Running within Docker / node:14.15.4-alpine3.12
Running Inside GCLOUD ( latency ~10ms )
After started, the app starts PINGING the redis server every 30 seconds
Server crashes after 4 minutes (usually), just after PING #8 ( PING timestamp === ERROR timestamp )
not a single event es registered in the log ( end, error, uncaughtException, reconnecting )
I’ve tried ECHO instead of PING but I got same results.

var redis__create_ping = ( client ) => {
        client.ping = setInterval(( )=>{
                let timestamp = ( new Date() ).getTime();
                client.instance.ping(  (error, pong ) => {
                        if( error ){
                                console.error( '\n<PING ERROR>', client.name, client.index );
                                console.error( error );
                        }
                        else {
                                if( __.DEBUG ){
                                        console.log( '\n<PING>', client.name, client.index, (new Date()).getTime() - timestamp );
                                }
                        };
                });
        },  30000);
};

var redis__connect = ( args , success, fail ) => {
        let { index, name } = args;
        let client = { name, index };
        let host = ___.REDIS.HOST;
        let port = ___.REDIS.PORT;
        let cli = redis.createClient({ host, port, db: index, socket_keepalive: true });
        cli.on('connect',  ready => {
                if( __.DEBUG ) console.info('\n<CONNECT>', name, index  );
                client.instance = cli;
                redis__create_ping( client );
                CLIENTS[name] = client;
                success( true );
        });

        cli.on('ready', () => {
                if( __.DEBUG ) console.info( '\n<READY>', name, index );
        });

        cli.on('reconnecting', () => {
                if( __.DEBUG ) console.info( '\n<RECONNECTING>', name, index );
        });

        cli.on('end', () => {
                if( __.DEBUG ) console.info('\n<END>', name, index  );
        });

        cli.on('uncaughtException',  error  => {
                console.error('\n<UNCAUGHT-EXCEPTION>', name, index  );
                console.error( error  );
        });

        cli.on('error', error => {
                console.error('\n<ERROR>', name, index  );
                console.error( error );
        });
};
