Subject Re: [users@httpd] What does this mesg mean? (Server cannot start)
Date Fri, 30 Nov 2012 19:32:19 GMT
This's very likely that Apache leaving a bunch of stray semaphore sets
lying around after an attempted restart of apache.

you can use the following commands to check:
#ipcs -s | grep apache

and use the following to kill:
ipcs -s | grep apache | awk ' { print $2 } ' | xargs -n 1 ipcrm -s

use the username you starts apache (e.g., specified by "User" directive)
instead of 'apache' in the commands.
