(0x800703E3) The io operation has been aborted because of either a thread exit or an application request

I faced a problem that i couldn't solve nowadays. If you share your opinions, i'll be appriciated.

The problem about streaming file.

For example, user comes from url with a queryString parameter that identify the file to stream.

And then, read the file from database succesfully. After that, i use below codes to stream and write into response's output

try
{
    do
    {
         read = reader.GetBytes(6, offset, chunk, 0, chunk.Length);
         if (read > 0)
         {
            if (streamParam.Context.Response.IsClientConnected)
            {                                         
                streamParam.Context.Response.OutputStream.Write(chunk, 0, (int)read);

                streamParam.Context.Response.Flush();

                offset += read;
             }
             else read = -1;
         }
     }
     while (read > 0);
}
catch (Exception exc)
{
    streamParam.Context.Response.End();
}

The most important thing is, i can't reproduce the error in debugging environment. But when i publish the website to server, i faced errors thousands times in Event Viewer.

I Shared the event log without stack trace in case of provide some tips or something like that,

P.S. : I researched it, server updates sp 2 and com port reset. It didn't worked. Also i read about IsClientConnected but it's currently in the code.

Any help will be great, thanks,
