git pull: Couldn't reserve space for cygwin's heap, Win32 error 0

When I tried to pull the code from git, it took so long and finally it said "Couldn't reserve space for cygwin's heap, Win32 error 0"

There are various discussions which I found over web. But the first thing which i tried was "restarting my windows system" and it worked for me!!
