How much RAM is expected to be present in the system to run valgrind
for 15-20 mins atleast.
There's no fixed number because it entirely depends on what you
are running valgrind on and which tool you are using.
Using the default tool (memcheck) which you appear to be you will
typically need a litle over double the memory your program would need
without valgrind because memcheck is keeping shadow state to tell it
which bits of your programs memory are initialised.
