Apache not running, httpd is down
[~]# service httpd restart
httpd not running, trying to start
Then i have checked the http error lod and found the following error
[Wed Oct 25 00:00:00 2011] [error] (17)File exists: Cannot create SSLMutex with file `/usr/local/apache/logs/ssl_mutex'
Configuration Failed
Solution:
cd /usr/local/apache/logs/
mv ssl_mutex ssl_mutex_ajeesh
service httpd restart
This fixed my issue.
