My webserver is getting full of  NullReferenceException.txt files....

 

I have a daily chat that starts as 11 am, before it´s starts the files begin to apear and it only stops at IIS automatic restart at 23:59 PM.

 

The files contain the same message:

 

System.NullReferenceException: Object reference not set to an instance of an object.
   at CuteChat.ChatPlaceUser.GetItemInfo(ChatConnection conn, String formsg, String& type, String[]& args)
   at CuteChat.ChatPlaceItem.RenderItemInfo(ChatConnection conn, String msgid)
   at CuteChat.ChatPlaceUser.OnRemoveForConnection(ChatConnection conn, String reason)
   at CuteChat.ChatPlaceItem.e(String A_0)
   at CuteChat.ChatManager.RemovePlaceItem(ChatPlaceItem item, String reason)
   at CuteChat.ChatManager.ClosePlaceConnection(ChatConnection conn, String reason)
   at CuteChat.ChatManager.Maintain()
   at CuteChat.ChatPortal.Maintain()

 

Any know reason to this?
