I have this kind of problem @schmidt-sebastian

i have 7 listeners, but always disconnecting some listeners and stop registering information in database. Im using Java.

What i have to do..to stop this behavior..?? because its intermitent situation.

I have to move to realtime database? or have some config extra to fix that? Because when i restart the server the listener back again..

Again, we are having a strange behavior of listeners. We have 7 listeners active and some time just 6..just 5.. and back to 7 ..but with this behavior we can put our plataform in production stage.

im using this

https://firebase.google.com/docs/admin/setup#java

implementation 'com.google.firebase:firebase-admin:9.2.0'

##########################

Resource resource = resourceLoader.getResource("classpath:prod-firebase.json");
    String fileLines = new BufferedReader(new InputStreamReader(resource.getInputStream(), StandardCharsets.UTF_8))
            .lines()
            .collect(Collectors.joining());
    InputStream serviceAccount = new ByteArrayInputStream(fileLines.getBytes());

    FirebaseOptions options = new FirebaseOptions.Builder()
            .setCredentials(GoogleCredentials.fromStream(serviceAccount))
            .setDatabaseUrl("realtimedatabaseurl") //we are using realtimedatabase 
            .build();
    FirebaseApp.initializeApp(options);

    databaseReference = FirebaseDatabase.getInstance().getReference();

    dbfirestore = FirestoreClient.getFirestore(); // firestore instance

the problem is higher workload .. i check three times the workload and if we see the listener drop when the workload if high. the clock below each graph show us.. everytime have a peak drop listener.

now..i dont know what to do.. :(

Can someone help me?
