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 + +Regards, +Andrey Tkach _______________________________________________ mono-bugs maillist - [email protected] http://lists.ximian.com/mailman/listinfo/mono-bugs
