Just to give you some debugging help for the future: you can get the
attachees to a shm segment with shmfs using fuser(1):

[root /root]# ipcs -m

------ Shared Memory Segments --------
key shmid owner perms bytes nattch status
0x00000000 32769 nobody 600 46084 11 dest

[root /root]# fuser -v /dev/shm/.IPC_00008001

USER PID ACCESS COMMAND
/dev/shm/.IPC_00008001
root 883 ....m httpd
root 886 ....m httpd
root 887 ....m httpd
root 888 ....m httpd
root 889 ....m httpd
root 890 ....m httpd
root 891 ....m httpd
root 892 ....m httpd
root 893 ....m httpd
root 894 ....m httpd
root 895 ....m httpd

The number in .IPC_######## is the shmid in hex.

So if you are in doubt which program is to blame, you should have a
way to find it now.
