Can't reproduce native exploit : only got 0 (of 64) pages

[BenjaminSchubert]

Hi !

First of all thank you very much for this comprehensive repository on rowhammer ! It is rare to see well documented research tools.

I'm trying to reproduce your native exploit on a ubuntu 16.04 computer and I only get lines like

[!] Can't hammer row 10531 - only got 0 (of 64) pages
[!] Can't hammer row 5835 - only got 0 (of 64) pages
[!] Can't hammer row 2689 - only got 0 (of 64) pages

Would you have any idea from where this could come from ? I don't get any other logging information.

Thank you very much.

memory seems to be very fragmented then. try to allocate more memory for rowhammer or to reboot the machine before, or both.
