Here are the code to increase the number of message queues.Before this the number of message queues that can be created is so limited,around 20 only.Now i can create around 100 message queues.

/* Set the file size resource limit. */

limit.rlim_cur = 4194304 ;
limit.rlim_max = 4194304 ;

The two lines above is very important.It will determined how many message queues can be created…

How do i solve it?I searched on Google and found about bcdedit.

So go to Accessories,then go to command prompt,run as administrator.Then type bcdedit.Choose the unused OS that you don’t want to use it.

Get it’s long number…i don’t now what is that.Something like key i guess.Put it like the message shown below.

Then type :bcdedit /delete {4c21825f-e04b-11dd-b760-00195b61617a}

Then settle.For more information ,you can visit http://www.sevenforums.com/tutorials/2676-bcdedit-how-use.html
