Semaphore error (semget)-Apache crash

The issue causes mainly due to insufficient disk space available for apache resources.

1. Check /etc/httpd/domlogs, if it is motre than 2GB that will cuase the issue; reduce the size and restart apache.
2. Check the error_log, access_log and other log files if anything is above 2B that will cause the issue; reduce the size and restart apache.
3. If the issue is due semaphore resources, then run the following script.


ipcs -s | grep nobody | perl -e 'while () {
@a=split(/\s+/); print `ipcrm sem $a[1]`}'

{ copy the above lines into a file and run the file using sh
eg: sh filename}

Then restart apache and this will fix the issue.
