Subject Re: [users@httpd] Help needed with event MPM configuration
Date Tue, 04 Nov 2014 19:36:00 GMT
Ok. Thanks.

Does this situation sound plausible - Keep alive connections are not being
used effectively by client applications (i.e. subsequent requests on
keep-alive connections are not frequent enough to keep Apache workers busy
all the time, resulting in low CPU utilisation). At the same time, because
there are already so many keep-alive connections, the server is not
accepting any more new connections from the client application. Thus, the
server is mostly idle but not accepting new connections.

Apologies for repeating the question, but wanted to confirm before I
proceed to change the configuration.
