User-Agent: Mozilla/4.0 (compatible; MSIE 5.0; Windows 98; DigExt)

Description of problem:
Default max. message queues in RedHat 6.2 is 128 but in RedHat 7.2 is
only 16.  All other ipc limits are increased except for this one for
no good reason.

Version-Release number of selected component (if applicable):


How reproducible:
Always

Steps to Reproduce:
1. ipcs -l and you can see it
2.
3.
	

Additional info:

This can be easily get around by changing the configuration.  I think
it's a mistake to be so small by default.  A value of 128 or 256 is
probably more appropriate.
