If you are having trouble with your Apache server software, you should take the following steps:
/usr/local/apache2/logs/error_log, but see the Apache has an active community of users who are willing to share their knowledge. Participating in this community is usually the best and fastest way to get answers to your questions and problems.
#apache on Freenode IRC is also available for user support issues.
If you've gone through those steps above that are appropriate and have obtained no relief, then please do let the httpd developers know about the problem by logging a bug report.
If your problem involves the server crashing and generating a core dump, please include a backtrace (if possible).
With millions of users and fewer than sixty volunteer developers, we cannot provide personal support for Apache. For free support, we suggest participating in a user forum.
Professional, commercial support for Apache is available from a number of companies.
