Hi again,
As i've written this it seems my primary intention is just to get arts,
but not i'm more worried why grsec stopping it (there is a reason for
this i think) and if i should *disable* grsec2 at all to overcome this
'BUG'.
Thanks

for the future, please post an url for such off-forum discussions, unlikely people will have the time/motivation to cross-post all over the net: http://marc.theaimsgroup.com/?t=109678729900001&r=1&w=2
