What is IPCS?


I have an error reporting on my console and I'm not sure what it means:

Code:
Can't attach shared memory(key=0x64), errno=12
the only thing i could find on google was this:

http://lists.us.dell.com/pipermail/l...ly/015638.html

ok, so run the ipcs -t command and read the output, so i did:

Code:
------ Shared Memory Attach/Detach/Change Times --------
shmid      owner      attached             detached             changed
0          root        Jan 23 14:50:38      Jan 21 01:33:29      Jan 14 01:15:25

------ Message Queues Send/Recv/Change Times --------
msqid    owner      send                 recv                 change
ok, well what does this really mean? so like any other user i went to the man page to find this under bugs:

Code:
This manual page is woefully incomplete, because it does not at all
     attempt to explain the information printed by ipcs.
that's where i got lost. what am I looking for here?

Start googling - here might be as good a start as any.
Issue the command without the "-t", and see what's really happening.
