1343------
1344
1345Maximum number of message queue ids on the system.
1346This value scales to the amount of lowmem. It is automatically recomputed
1347upon memory add/remove or ipc namespace creation/removal.
1348When a value is written into this file, msgmni's value becomes fixed, i.e. it
1349is not recomputed anymore when one of the above events occurs.
1350Use auto_msgmni to change this behavior.
