Application Error: faulting application w3wp.exe, version 6.0.3790.0, faulting module ntdll.dll

And we have the same thing. More details:

I have a certain aspx page that worked perfectly under .net 1.1 runtime, windows 2003 and IIS6. When we upgraded to .net 2.0, this aspx page breaks ONLY when it hasn't been called for 10 or 15 minutes. At which time several errors post to the Event Log, including:

(1) .NET Runtime version 2.0.50727.42 - Fatal Execution Engine Error (7A05E2B3) (80131506)

(2) Faulting application w3wp.exe, version 6.0.3790.0, stamp 3e8000e6, faulting module mscorwks.dll, version 2.0.50727.42, stamp 4333e7ec, debug? 0, fault address 0x000e9f96.

Sometimes at this point IIS completely blows up and reports SERVICE UNAVAILABLE when hitting any web page, and you have to restart IIS.

After restarting IIS (or not, if IIS is still running), if I hit that same aspx page again within a few minutes, it works fine this time. I can hit the page over and over again, if done within minutes or seconds of each other. But if I wait about 15 minutes or more and try again, BOOM. Same errors in event log.

Now if my aspx page has errors, why was it fine in .net 1.1? And why is .net 2.0 so unstable that it falls over and dies as the result of a simple aspx page? Here is the source of my page:

<%@ Page language="c#" AutoEventWireup="true" %>
<%@ Import Namespace="System.IO" %>

<script runat="server">
            private void Page_Load(object sender, System.EventArgs e)

                  //try

                  Regex Exp = new Regex("clientid=[0-9]+", RegexOptions.IgnoreCase);
            
                  if(Bytes > 0)
                  {
                        //page was hit programmatically by Brava client / generic.dll
                        BinaryBuffer = Request.BinaryRead(Bytes);
                        System.Text.UTF8Encoding utf8 = new System.Text.UTF8Encoding(true);
                        PostedData = utf8.GetString(BinaryBuffer);

                        string strClientID="";
                        foreach(Match m in Exp.Matches(PostedData))
                        {
                              strClientID = m.Value.ToLower().Replace("clientid=", "");
                              tmpClientID=Convert.ToInt32(strClientID);
                        }

                RetVal = this.GetClientID(tmpClientID);
                        NewPostedData = PostedData.Replace(tmpClientID.ToString(),RetVal); //REPLACE(PostedData,ClientID,RetVal);
      
                        Response.ClearHeaders();
                        Response.Clear();
                        Response.Charset = "UTF-8";

                        Response.Write(NewPostedData); //this line is crucial - it's sending http back to the activex brava client
                  }
                  else //page was hit directly, via browser
                        Response.Write("This test must be performed from the Admin screen, under the <B>Troubleshoot</B> section.");
            }
   
        private string GetClientID(int clientid)
        {
            int dwTime = clientid; //dwTime is set to the clientid coming in

            char[] sResult = "0000-0094".ToCharArray();  // should be length of 15
 
            int[] pickOrder = {5,9,8,4,6,11,7,2}; // ignore first and last 2
         
            for (int i = 7; i >= 0; i--)
            {
                int val = dwTime & 0xf;
                dwTime >>= 4;
                sResult[pickOrder[i]] = "0123456789ABCDEF"[val];
            }

            return new String(sResult);
        }

I need this issue closed. It ended up being a confirmed BUG in .NET/CLR 2.0. Microsoft is working on a hotfix. I don't want this deleted, though, because it might help someone.

carp3d: I have 3 new dotnetruntime dll's from microsoft, that they gave us to see if it solved the bug, and it did. They are not for distribution, but I'll give them to you if you want to find out if it solves your issue. Let me know.

Could you please send me the 3 new dotnet runtime  "dlls" that you have , So, I can test it here and confirm that it's the same issue I have.
Thank you for sharing the info.
I ahve been goin on on this with out any information for a long time.
Thank you.

dll's sent. it's 3mb in a zip. please let me know if that solves your problem.

This is to SweatCoder , Hi, I didn't recieve the "dll's" you sent . Please let me know where I can access them or is there a place you can put them on in thsi site ?.
Thank you,
Sunita

I'll take the dlls to see if they possibly resolve my issue. Do you need an email?  Im amazed that my experience has been so isolated thus far.

carped

Here you go:

http://www.builderdash.com/dotnet20fix.zip

After backing up your original 3 dll's, put the new ones here:
C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727

These dll's are ALPHA, largely untested, and not for production. Use them in dev/test only. When I receive a true hotfix from MS, I'll come back to this thread and post.

I would be very interested to hear back from carp and suni whether this fixes your problem, as it fixed ours. You may need to restart IIS or reboot before the fix kicks in, but I'm not sure about that.

Thx guys....

I still am using the 1.1.4 version and so, I am guessing I can still try these dll's .
If you think I am wrong , please let me know.
Thank you,
sunita

1.1.4? you're not using .net 2.0? the bug we found exists exclusively in 2.0.

yeah, The error happening is on 1.1

I now have the official hotfix, but it only works on 2.0.

Who do I contact at Microsoft to see if they have a solution for the 1.1 ?
Under 1.1 I ahve the 2 of the dll's that you sent , but I didn't find the  "mscordacwks.dll"  though. I guess thsi one is new .

Thank you,
Sunita

you'll have to open a support incident with them, and i'm sorry i no longer have the phone number.

Good morning SweatCoder. . .

I seem to be having a similar issue. Do you have a link for the official hotfix for 2.0?

Thanks.

I got the official hotfix. I would be interested to learn if it solves others' problems with .net 2.0.

Can anyone tell me where to find the dotnet2 fix discussed above?

Many thanks,

JG

That fixed was rolled into a service pack for win2003. I don't remember which one, either sp1 or (sp2?).
