Subject: Error on Reconnect
Hi Guys!

I'm getting this error when the app try to reconnect:

at System.ThrowHelper.ThrowArgumentException(ExceptionResource resource)
   at System.Collections.Generic.Dictionary`2.Insert(TKey key, TValue value, Boolean add)
   at Matrix.Xml.Xpnet.NamespaceStack.Init()
   at Matrix.Xml.XmppStreamParser.Reset()

   at Matrix.Xmpp.Client.XmppClient.CleanupSession()
   at Matrix.XmppStream.socket_OnDisconnect(Object sender, EventArgs e)
   at Matrix.Net.BaseSocket.FireOnDisconnect()
   at Matrix.Net.ClientSocket.Disconnect()
   at Matrix.Net.ClientSocket.Send(Byte[] bData)

   at System.Threading.QueueUserWorkItemCallback.System.Threading.IThreadPoolWorkItem.ExecuteWorkItem()
   at System.Threading.ThreadPoolWorkQueue.Dispatch()
   at System.Threading._ThreadPoolWaitCallback.PerformWaitCallback()

I think it's a problem in the library(MatriX.2.0.0.21) but could be in my code?

The error it's been raised after made a Close() and then an Open().

Regards.

  • are you waiting until you get the OnClose event?
  • Have you tried to create a complete new XmppClient object for your new connection?

Hi Alex!

Yes, we are handling the OnClose event.
The problem looks like is raised by some users wich suspend their devices or loose their internet connectivity and when the app try to reconnect have that error. The error is not present every time in every device but the cases are enought to take it in care.

Best regards.
