+Summary: mono web + remoting failing load test
+
+Description of Problem:
+
+Here is attached the test sample of using web + remoting. We have blocking
+trouble while trying to test our application that uses such model under load.
+
+While flooding attached application with requests, mod-mono-server stops
+responding very soon. You may take a look at screenshots that are packed in
+zip file with application:
+
+* test_win2003serv_50_users.jpg - Test Center emulates 50 connections, both
+client & server are running on windows server 2003 (P4 3GHz, 1GB RAM).
+Graph is relatively smooth. Amount of requests sent by application Test
+Center & ab2 coincides with registered by RemoteServerSample application.
+
+* test_suse10_1_20users.jpg - Test Application is deployed on Suse Linux
+10.1 (Dual Xeon 2,8 Ghz with 8 GB RAM) with installed mono-1.1.17.1 and
+mod_mono-1.1.17.0. In spite of the configuration, the server falls nearly
+just after running, even on test with 20 connections emulation. Difference
+between Total Requests & HTTPErrors results total amount of request that
+were registered on server (about 6000 registered  from ~52000 of total!).
+
+After such test apache with mod-mono-server stops responding until restart
+process or (sometimes) system reboot.
+
+
+Steps to reproduce the problem:
+1. start sample server. Unpack attached sources.
+suse:~/projects/RemoteServerSample/bin/Debug# mono RemoteServerSample.exe
+
+2. deploy TestLoadControl to apache
+   on the WebConfig there is App Settings key "ConnectionString" that poins
+to server location. By default it looks into localhost.
+
+3. Run MS App Center test or ab2 test to flood TestLoadControl application
+with requests. Application calls to remote server every time when Page_Load
+event happens.
+
+To notice this with ab2:
+
+	ab2 -n100000 -c50 http://localhost/TestLoadControl/index.aspx
+and 
+
+keep an eye on RemoteServerSample.exe console and ab2 output. You can
+notice ratio "Amount of registered on server requests/amount of sent requests"
+
+
+
+Actual Results:
+are seen on test_suse10_1_20users.jpg
+
+Expected Results:
+are seen on test_win2003serv_50_users.jpg
+
+How often does this happen? 
+always
+
+Additional Information:
+Feel free to forward bug to real buggy component owner. This might be
+mod_mono, remoting, GC etc
