-- When trying to start or stop Gateway the following error can be observed, either in command line or in a trace file (SYS.out, SUP.out):

-- 2011/10/19 10:11:23 - ERROR from SmwQueueOpen
  2011/10/19 10:11:23   msgget failure: (28) No space left on device

* The error is generally encountered when the Operating System cannot open additional IPC message queues (due to configuration limits).

To solve this:

1. Determine the number of messages queues already opened:
ipcs -a (or ipcs -q)

2. Determine the number of IPC message queues needed by Gateway.
Typically Gateway needs 7 message queues when using only one protocol but the need may increase while activating additional protocols and/or dynamic processes.

3. Increase the number of IPC message queues (msgmni)
For exemple:
echo  100 > /proc/sys/kernel/msgmni

4. Restart Gateway
