It means that your apache hasn't been shutdown properly - it failed to remove
the shared memory segments it allocated. You have two options at this point:

- reboot the server
- use the ipcs -m command to list the shared memory segments and then ipcrm -m
shmid for each of the former apache segments (you can tell which belonged to
apache by the owner - it will be the user apache runs as). Before removing the
segments, though, make sure that you stop apache.

hope that helps,
