Hi,

You will have to kill the active semaphore processes in order to start Apache service successfully.

To list the PIDs of the active semaphore processes

ipcs -s

If seen more than one process you use this script to delete all semaphores

ipcs -s | grep nobody | awk '{print $2}' | xargs -n 1 ipcrm sem


Try to restart apache now.

Hi,

The above tweak will fix the issue temporarily as it will re-occur when Semaphores get full.


To fix this permanently, you can increase the limit of Semaphore in the server.

Add the following lines in the file /etc/sysctl.conf

kernel.msgmni = 1024
kernel.sem = 250 256000 32 1024
