Thread aborting issue with Sharp Svn with C#.Net 4.0

Question

I have developed ASP.net application using VS-2010, C#.Net 4.0 with SharpSvn dll. When I'm working with dev server(don't have 3-Tier Architecture), it works fine. But when we are working with QA environment(have 3-Tier Architecture) it gives thread abort exception most of the time.Following shows the code and error log I have. Any help on this really appreciate.

public bool Checkout(string svnurl, string target)
    {
       try
        {
            using (_client = new SharpSvn.SvnClient())
            {
                _client.LoadConfiguration(Path.Combine(Path.GetTempPath(), "Svn"), true);
                _client.Authentication.DefaultCredentials = new TNetworkCredential(_username, _password);
                _client.Authentication.SslServerTrustHandlers += SvnSslOveride;
                var targetsvn = new SvnUriTarget(svnurl);

                if (_client.CheckOut(targetsvn, target))
                {
                    Log.Info("Successfully checked out to following location : " );
                    Log.Info(target);
                    return true;
                }
            }
            Log.Info("Unable to checkout "+ svnurl +" Svn location to target location : ");
           Log.Info(target);
            return false;
        }
        catch (Exception ee)
        {
            Log.Error("Error:SvnClient checkout....");
            Log.Error(ee);
            throw ee;
            return false;
        }
    }

private static void SvnSslOveride(object sender, SvnSslServerTrustEventArgs e)
        {
            e.AcceptedFailures = e.Failures;
            e.Save = true;
        }

error log

I missed <httpRuntime executionTimeout="(time in seconds)"> tag in web config and it automatically set by IIS server. The default is 110 seconds. Note :In the .NET Framework 1.0 and 1.1, the default is 90 seconds. After I added following line to web.config and it works fine.

<httpRuntime executionTimeout="600">

Previously it works sometimes because the time taken to SVN checkout in DEV server is less than in other environment because of the size of the repositories and network connections. Thanks all for your answers
