Subject Re: [users@httpd] Apache intermittent crash - HELP!!!
Date Thu, 17 Dec 2009 05:05:41 GMT
Hi daniel,

1. the intermittent crash happens even before we did any performance tuning
of the apache.

2. the reason why we did the tuning is because we want to limit the apache
memory usage which previously was due to apache using up all the swap mem
causing the crash.
