If I stress-test the site with : ab -c 2 -n 20 http://sitename/ it kills apache. If I stress-test the site with : ab -c 50 -n 1500 http://sitename/static.html it works fine. I have set apache's errorlog to debug. But it writes nothing, either in the virtualhost or in the server-file. Can anyone give a hint about what can be wrong? What do you mean with 'kills apache', does it terminate apache or does apache hang (eg. 100% cpu), and respond normal after the stress test is over? And what is the index of your site? A php script, or..? Do you have ModRewrite redirects etc? - Matijn -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
