Hi Khaled,

I think this might be because the virtual memory space hardcoded to be 
used MMTk is also getting mapped by C library stuff.

You could try one or both of the following:

(1) Try to reserve the virtual memory eagerly by running with 
-X:gc:eagerMmapSpaces=true

(2) Adjust the virtual memory ranges in the appropriate config file 
build/targets/??.properties

Cheers,
Mike

I am getting the below error when I use malloc from system call.

Any ideas or solution ?
