crash analysis

Hi,

My application is running on 65 PC.
After a few hours, this applications crash on 2-3 PC.
I get no exception in my log files.
I set the Application.ThreadException and
AppDomain.CurrentDomain.UnhandledException exception event handlers.
The last one is triggered with 'System.NullReferenceException: Object
reference not set to an instance of an object.' but there is no stack
trace available.
I got no dump file, no popup window.
I only get the following entry in the event log :

Event Type: Error
Event Source: .NET Runtime 2.0 Error Reporting
Event Category: None
Event ID: 1000

Hi,

So AppDomain.CurrentDomain.UnhandledException is catching an exception,
it's just that you don't know where it originated , right?

Are you compiling your app in debug mode and copying the pdb file to the
machines?

Are you dumping the content of UnhandledExceptionEventArgs ?
inside you should find more info regarding what happened.

Yes you are right.

still yes.
Are you dumping the content of UnhandledExceptionEventArgs ?

Here is the code :

private static void CurrentDomain_UnhandledException (object sender,
UnhandledExceptionEventArgs e)
{
try
{
string message = e.ExceptionObject.ToString();
if(message.ToUpper().IndexOf("THREADABORTEXCEPTION ") == -1)
{
System.IO.StreamWriter sw = new System.IO.StreamWriter
("IpdRouting_Unhandled.LOG", true);
sw.WriteLine (System.DateTime.Now.ToShortDateString () + " @
" +
System.DateTime.Now.ToLongTimeString () + ">\t" +
message);
System.Text.StringBuilder sb = new System.Text.StringBuilder
(2048);
Exception currentExc = null;
for (currentExc = (Exception) e.ExceptionObject;
currentExc != null; currentExc =
currentExc.InnerException)
{
sb.AppendFormat ("{0}\r\n{1}\r\n{2}\r\n",
currentExc.GetType ().FullName,
currentExc.Message,
currentExc.StackTrace);
}
sw.WriteLine (sb.ToString ());
sw.Flush ();
sw.Close ();
}
}
catch
{
//Application.Exit();
}
}

I appreciate your help.
Besides, it is very urgent for me.
Thanks a lot.
