hi,
for an unknown reason the server restart by itself maybe i have done something wrong.
with photon v3-0-19-2868-RC8

here is my code:

the code of the constructor: of Proto.Operations.Kick: 
public Kick(OperationRequest request)
        {
            this._operationCode = request.OperationCode;
            if (request.Parameters.Count != 2)
            {
                this._isValid = false;
                this._returnCode = (short)Proto.ErrorCodes.Type.InvalidParametersNumber;
                this._returnMessage = "to much or not enough parameters";
            }
            this.Name = request.Parameters[0] as string;
            this.Reason = request.Parameters[1] as string;
            if (null == this.Name || null == this.Reason)
            {
                this._isValid = false;
                this._returnCode = (short)Proto.ErrorCodes.Type.InvalidParametersType;
                this._returnMessage = "one or more parameters are in a wrong type";
            }
        }

the code of the operation threatment:

private void OpKick(OperationRequest operationRequest, SendParameters sendParameters)
        {
            var r = new Proto.Operations.Kick(operationRequest);
            if (r.IsValid)
            {
                if (r.Name != this.NickName)
                {
                    if (!RoomManager.GetInstance().KickPlayer(r.Name, r.Reason, this))
                        r.ReturnCode = 1;
                }
                else
                    r.ReturnCode = 1;
            }
            this.SendOperationResponse(r.CreateOperationResponse(new Dictionary<byte, object>()), sendParameters);
        }

then the create operation response code: 
public Photon.SocketServer.OperationResponse CreateOperationResponse(Dictionary<byte, Object> parameters)
        {
            var r = new OperationResponse(this._operationCode, parameters);
            r.ReturnCode = this._returnCode;
            r.DebugMessage = this._returnMessage;
            return r;
        }


and what vs2010 attached debugger says:
A first chance exception of type 'System.Threading.ThreadAbortException' occurred in mscorlib.dll
The thread 'ThreadFiber-1' (0xb00) has exited with code 0 (0x0).
A first chance exception of type 'System.NullReferenceException' occurred in PhotonHostRuntime.DLL
A first chance exception of type 'System.Exception' occurred in PhotonHostRuntime.DLL

here is the photon server log:
3492: 12:15:35.963 - CManagedHost::OnStackOverflow()
3604: 12:15:36.065 - CManagedHost::OnDomainUnload() - 5

3604: 12:15:37.564 - Application: "Phtn3srv" restart complete.

i just want to know what im doing wrong and if the problem comes from my code or a problen due to photon

EDIT: i forget to precise that the problem comes when r.Name is equal to this.NickName (those variables are valid string).

    Hard to say whats going wrong. From the exception i expect that one of the provided string is null (A first chance exception of type 'System.NullReferenceException' occurred in PhotonHostRuntime.DLL).
    You should put a try catch around the code in your OpKick method to get more details about the exception.

    Nothing in my code is null everything is valid the exception is throw under photon when im sending an operation response and the thread is cancelled into photon so i cannot catch anything the server just reboot maybe its a probem in my funtion 
    CreateOperationResponse

    I realy dont know how to fix this and if it's my fault what im doing wrong.

    Just another question to the photon developpers: are the peers runned into a thread context maybe it come from that.
    EDIT: in fact the server reload the domain when the operationresponse return code is different from 0;

    Your code looks correct.
    I'am currently trying to simulate your OperationResponse in my local machine with the following code.
                var r = new OperationResponse(0, new Dictionary<byte, object>());
            r.ReturnCode = 1;
            r.DebugMessage = null;
            this.SendOperationResponse(r, sendParameters);
            return;

    Unfortunately no exception occurs on my machine.
    Are these the parameters which are set when you send the operation response ?

    yeah it's what im sending but i have a class who do that with this line: 
    this.SendOperationResponse(r.CreateOperationResponse(new Dictionary<byte, object>()), sendParameters);
    this is in my custom peer class who inherits from PeerBase.
    i construct a class who generate the operations response : Proto.Operations.Kick (in order to avoid numerous line of code in a same file).
    but the content in the OperationResponse generated is valid.
    I have tested with your code suggestion and is the same problem.

    Which version of PhotonSocketServer are you using (bin_Win32, bin_Win64, ect. ) ?
    And which protocol is used (Udp, Tcp) ?

    Hi, i'm on the same team as Massou, on the client side we use: Photon3Unity3D.dll 3.0.1.2
    The callback generated on the client is:
    @: public void OnStatusChanged (StatusCode statusCode)
    case StatusCode.DisconnectByServerLogic: { Debug.Log("OFFLINE [3]"); _isConnected = false; break; }

    Edit: my peer is initialized like this:
    _peer = new PhotonPeer(this, ConnectionProtocol.Udp);

    If it may help ;) Thanks in advance :)

    For this particular issue, yes, you are the only persons who got this. At the moment, we have no other crashes to investigate and it's really hard to say anything until we could reproduce the issue.

    Would you zip your projects and make them available to us? You could remove anything that's not necessary to reproduce this but should make sure we have client and server code that causes this issue.
    This would help tremendously.

    We found the BUG :evil:

    public short ReturnCode { get { return this._returnCode; } set { this.ReturnCode = value; } }

    The setter of this property calls himself which results in an infinite loop.
    This is the reason why you were not able to catch the exception. The .Net runtime throws a StackOverflow exception which cannot catched.
    See the MSDN documentation for more information.

    http://msdn.microsoft.com/en-us/library ... n(v=vs.100).aspx
    Starting with the .NET Framework version 2.0, a StackOverflowException object cannot be caught by a try-catch block and the corresponding process is terminated by default.
