Subject Re: [users@httpd] Apache crashes under keep-alive test
Date Tue, 12 Apr 2011 21:23:39 GMT
Try this settings -

1) <IfModule mpm_prefork_module>
   StartServers            20
   MinSpareServers     20
   MaxSpareServers     50
   ServerLimit         1000
   MaxClients          1000
   MaxRequestsPerChild 100000
</IfModule>

2) As Jim suggsted - Timeout should be maybe 10 and KeepAliveTimeout
maybe 3. increase MaxKeepAliveRequests to higher no. may be 600

3) Make sure Tsung is using keepalive aonncetions

Let's know how it goes?
