@yanmasharski Please can you share some of the code you use to manage your socket. Also when you mention that an RPC might be in progress is it an RPC over the socket or client object?

yanmasharski commented 2 years ago

RPC is running over client objet.

socket = client.NewSocket();
        try
        {
            await socket.ConnectAsync(session, true, 30);
        }
        catch
        {
            return;
        }

        socket.Closed += OnSocketClosed;
        socket.ReceivedError += OnReceivedException;

And we reconnect the socket after a 2-second delay if it was closed or if we got an exception and the socket is not connected. For reconnection, we use the following code

var connectTask = socket.ConnectAsync(session);
 await connectTask;
 var joinChatTask = socket.JoinChatAsync(channelId, channelType, true);
        var result = await joinChatTask;

var connectTask = socket.ConnectAsync(session, true, 30);

yanmasharski commented 2 years ago

The issue was solved by closing sockets on an app pause

private void OnApplicationPause(bool p)
    {
        if (p)
        {
            socket.CloseAsync();
        }
}
